     Not sure what the most proper way to do division for it, but if you look through all the parameters operator/ and operator/= take, you would notice that:

     • operator/ takes in either std::complex<T> or T . So if you have your original complex created with double, then it should only take in another value that is either double or complex<double>.
     • In fact, depends on the compiler you are using, clang straight up gave invalid operands to binary expression ('std::complex<double>' and 'int') error

     operator/= takes in std::complex<T> or T, while also have specialization for float, double, and long double.

     • operator/= takes in std::complex<T> or T , while also have specialization for float , double , and long double . That means whatever passed to operator/= would have a change to be implicit converted to float, double, or long double, which int can do.

   • what is the value assigned to "bintag" after this line "binTag := field.Tag.Get("binary")" where field is one of the struct field in GOLang

     Top Answer

     See the StructTag documentation for a description of the tag format.

     See the StructTag example and the StructTag.Lookup examples examples of tags.

     The value of binTag is "" because the tag does not contain a value for the key "binary", nor does the tag following the convention for formatting struct tags.

     This code shows how to access the tag:

     v := reflect.TypeOf(T{})sf, _ := v.FieldByName("f1")fmt.Println(sf.Tag) // prints "f one"fmt.Println(sf.Tag.Get("binary")) // prints blank line

     Here's an example with a valid tag with key "binary":

     type U struct { g1 string `binary:"hello"`}v := reflect.TypeOf(U{})sf, _ := v.FieldByName("g1")fmt.Println(sf.Tag) // prints binary:"hello"fmt.Println(sf.Tag.Get("binary")) // prints hello

   • what is the type of field in MYSQL that Can store Integer or Double Values I mean in the same column you can store integer || Doubles ?

     Top Answer

     Answered Jan 30, 2013 · 0 votes

     I don't think there is such data type in mysql. Probably you might want varchar instead, and cast to the right data type in your server side code(php, java ...), but it might cause performance overhead. I'm not sure how come you have a such strange data type requirement. If the data has to be stored in this way, consider add an extra column for flagging data type.

   • what is the largest unsigned integer that is valid to store in the size field of a tar archive header

     Top Answer

     Answered Oct 25, 2018 · 2 votes

     According to the standard documentation

     The name, linkname, magic, uname, and gname are null-terminated character strings. All other fields are zero-filled octal numbers in ASCII. For historical reasons, a final NUL or space character should also be used.

     Therefore, 11 bytes give you 11 octal digits (0..777777777778, or 0..0x1FFFFFFFF range), which your program needs to convert to binary representation in a way that you find suitable - for example, like this:

     uint64_t size;sscanf(header->size, "%" SCNo64 "", &size);

     Demo.

   What is the field of complex numbers?

   • The field of complex numbers, denoted by ℂ, is the set of all ordered pairs of real numbers together with the following arithmetic operations. Addition: z ₁ + z ₂ = ( x ₁ + y ₁ j) + ( x ₂ + y ₂ j) = x ₁ + x ₂ + j ( y ₁ + y ₂). Substraction: z ₁ − z ₂ = ( x ₁ + y ₁ j) − ( x ₂ + y ₂ j) = x ₁ − x ₂ + j ( y ₁ − y ₂).

   What is a set of complex numbers?

   • The set of complex numbers is one of the three sets above equipped with arithmetic operations (addition, subtraction, multiplication, and division) that satisfy the usual axioms of real numbers. While addition and subtraction are inherited from vector algebra, multiplication and division satisfy specific rules based on the identity j ² = -1.
