   • Definition of math_sin function in the CPython source code?

     Top Answer

     Answered Apr 18, 2019 · 9 votes

     math_sin is defined via the FUNC1

     macro:

     FUNC1(sin, sin, 0, "sin($module, x, /)\n--\n\n" "Return the sine of x (measured in radians).")-

     where FUNC1

     is defined as:

     #define FUNC1(funcname, func, can_overflow, docstring) \ static PyObject * math_##funcname(PyObject *self, PyObject *args) { \ return math_1(args, func, can_overflow); \ }\ PyDoc_STRVAR(math_##funcname##_doc, docstring);

     so the preprocessor expands this to:

     static PyObject * math_sin(PyObject *self, PyObject *args) { return math_1(args, sin, 0); } PyDoc_STRVAR(math_sin_doc, "sin($module, x, /)\n--\n\n" "Return the sine of x (measured in radians).");

     (but then all on one line, and with the PyDoc_STRVAR macro also having been expanded)

     So math_sin(module, args) basically is a call to math_1(args, sin, 0), and math_1(args, sin, 0)

     calls math_1_to_whatever(args, sin, PyFloat_FromDouble, 0)

     which takes care of validating that a Python float was passed in, converting that to a C double, calling sin(arg_as_double), raising exceptions as needed or wrapping the double return value from sin() with the PyFloat_FromDouble function passed in by math_1() before returning that result to the caller.

     sin() here is the double sin(double x)

     function defined in POSIX math.h

     .

     You can, in principle, preprocess the whole Python source tree and dump the output into a new directory; the following does presume you successfully built the python binary already, as it is used to extract the necessary include flags for gcc:

     find . -type d -exec mkdir -p /tmp/processed/{} \;(export FLAGS=$(./python.exe -m sysconfig | grep PY_CORE_CFLAGS | cut -d\" -f2) && \ find . -type f \( -name '*.c' -o -name '*.h' \) -exec gcc -E $FLAGS {} -o /tmp/processed/{} \;)-

     and then math_sin will show up in /tmp/preprocessed/Modules/mathmodule.c.

     Or you can tell the compiler to save preprocessor output to .i files with the -save-temps flag:

     make clean && make CC="gcc -save-temps"-

     and you'll find make_sin in Modules/mathmodule.i.

   • Definition of range of a data type

     Top Answer

     Answered Jun 04, 2009 · 12 votes

     A data type is an abstraction that is applied to a chunk of memory to see that piece of memory as an area that can represent a value.

     For example, a single byte consists of 8 bits of memory. In the following diagram, each bit is represented by an underscore (_):

     byte: _ _ _ _ _ _ _ _ <- 8 bits-

     Since we have 8 positions where we can input either an 0 or 1 (as each memory bit can only be set to an on or off state -- hence binary), so we can have 2^8 or 256 combinations of distinct values we can represent from the 8 bits.

     This is were the concept of range comes into play -- how do we allocate those 256 combinations of values to an usable range?

     One way is to take the first of the 256 combinations as a 0, and the final combination as 255:

     byte: 0 0 0 0 0 0 0 0 <- Represents a "0"byte: 0 0 0 0 0 0 0 1 <- Represents a "1" .. so on ..byte: 1 1 1 1 1 1 1 0 <- Represents a "254"byte: 1 1 1 1 1 1 1 1 <- Represents a "255"

     For this data type, the range is from 0 to 255. This type is generally called an unsigned byte, as the values it can represent is unsigned as it has no sign. Basically, it is handled as if it were all positive numbers.

     On the other hand, since we have 256 combinations, what if we assign half of them as postive numbers while the other half is negative numbers? So, we assign a positive or negative value to a byte representation:

     byte: 0 1 1 1 1 1 1 1 <- Represents a "127"byte: 0 1 1 1 1 1 1 0 <- Represents a "126" .. so on ..byte: 0 0 0 0 0 0 0 1 <- Represents a "0"byte: 0 0 0 0 0 0 0 0 <- Represents a "0"byte: 1 1 1 1 1 1 1 1 <- Represents a "-1" .. so on ..byte: 1 0 0 0 0 0 0 1 <- Represents a "-127"byte: 1 0 0 0 0 0 0 0 <- Represents a "-128"

     The above representation is called a "two's complement" system, and the table above has been adapted from the Wikipedia article on two's complement.

     With this type of representation, in the same 8-bits, we could define a way to represent a range of numbers from -128 to 127. This representation is generally called a signed byte, because it is a byte type that can have both positive and negative representations of the number.

     In comparing unsigned byte and signed byte, their ranges are different:

     unsigned byte : 0 - 255signed byte : -128 - 127

     However, they are both have 256 possible combinations of values they can represent. They only differ by the range of values they can represent. That's the range of a data type.

     Similarly, this can be extended to int, long, float, double types as well. The number of bits that are assigned to each data type is different. For example:

     int: _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ <- 16 bitslong: _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ <- 32 bits

     Note: The actual number of bits for each type, such as int

     and long

     can be implementation- and architecture-dependent, so the above chart is not necessarily true.

     In the above chart, the int type is represented by 16-bits, which is 2^16 or 65536 combinations of values that it can represent. Again, like the byte, the range of values can be all positives or split into positive and negatives:

     unsigned int : 0 - 65535signed int : -32768 - 32767

     (Again, int

     does not necessarily have to be 16-bits.)

     Floating point types such as float and double are also represented by a bits in memory, but their data representation differs from integer data types such as byte and int in that they will store a value in memory as binary fractions and exponents. Floating point types also do have the concept of ranges as well.

     For the nitty-gritty details about how floating point values are defined and calculated in modern systems, please refer to Wikipedia has an article on the IEEE-754.

     Data ranges of a data type arises from the combinations of values which can be represented from the amount of memory assigned for a single unit of the single data type, and how those possible combinations are assigned to actual values that they represent.

     Range means the maximum and minimum value that can be stored inside the variable of a given type. For example if you have unsigned char and if we assume that the size of the datatype is 8 bits then you can store values ranging from 0 - 2^8-1 i.e. 0-255 inside it.

   • math.acos math domain error within the range of acos

     Top Answer

     Answered Sep 20, 2016 · 1 votes

     When I run your code:

     import math-def foo(x, y): x1, x2, x3 = x y1, y2, y3 = y s1 = math.sqrt(((x2-x1)**2)+((y2-y1)**2)) s2 = math.sqrt(((x3-x2)**2)+((y3-y2)**2)) s3 = math.sqrt(((x3-x1)**2)+((y3-y1)**2)) num1 = (s1**2)+(s2**2)-(s3**2) den1 = (2)*(s1)*(s2) theta1 = math.acos(num1/den1) num2 = (s1**2)+(s3**2)-(s2**2) den2 = (2)*(s1)*(s3) print repr(num2), repr(den2) print repr(num2 / den2) theta2 = math.acos(num2/den2) num3 = (s3**2)+(s2**2)-(s1**2) den3 = (2)*(s3)*(s2) theta3 = math.acos(num3/den3)foo([0, 4, 1], [0, 4, 1])

     I get that num2/den2 == 1.0000000000000004. Unless you print out the full precision, you might not notice that num2 is slightly bigger than den2 which results in a value slightly bigger than one. Obviously, since the maximum of cosine is 1, then you can't take the arcos of a number larger than 1.

   • Math function to find the biggest multiple of a number within a range

     Top Answer

     Answered Aug 28, 2018 · 4 votes

     You can employ modulo for this. For example, to calculate the biggest multiple of 4 that is less or equal than 13:

     13 % 4 = 113 - 1 = 12-

     in python, that could look like this:

     def biggest_multiple(multiple_of, input_number): return input_number - input_number % multiple_of-

     So you use it as:

     $ biggest_multiple(4, 9)8$ biggest_multiple(4, 12)12
