     Assuming you have a mix of numeric and non-numeric, this should work to return all decimal values that are not whole dollar amounts:

     Select * from tablename where colname like '%.%' --Has a decimal (as in original query)and colname not like '%.00' --Does not end with 00-

   • How do you write a program in javascript that asks the user to enter a list of numbers, and then find the average of the numbers

     Top Answer

     Answered Jun 20, 2020 · 1 votes

     You can only use a variable that holds the sum of the numbers entered and then just divide it by the total numbers entered.

     First approach infinite loop :

     The first approach acts as the one you're using. Basically, we'll ask for a new number as long as we don't get the string "XXX".

     /** * @const output the span where to print the average.**/const output = document.getElementById('output');/*** @var avg stores the sum of the entered numbers.* @var i keeps track of the number of numbers entered.**/let sum = 0, i = 0; /** basically while true increment i **/while (1 && ++i) { /** ask for a number or "XXX" to exit **/ const n = prompt(`Enter a number or enter "XXX" to exit :`, 0); /** if "XXX" is entered break the loop (the only way to break that infinite loop) **/ if(n == 'XXX') break; /** if something else than "XXX" is entered try to cast it to a float **/ sum += parseFloat(n);}/** print the average **/output.textContent = (sum / (i - 1)).toFixed(2); /** why dividing by "i - 1" and not only "i" is because "i" is incremented even when we enter "XXX" **/

     This approach is not user friendly (the loop can't be exited unless "XXX" is typed) and may consume a lot of resources.

     Second approach fixed number of numbers :

     This approach asks the user to enter how many number he want to type then we ask him to type as many numbers as the one he typed earlier.

     const output = document.getElementById('output');/*** @var n the number of numbers the user is going to type.* @var sum the sum of these numbers.* @var i a counter used to exit the loop when we reach "n" nummbers typed. **/let n = prompt('How many element do you want to enter ?', 2), sum = 0, i = 0; /** while i + 1 < n and no need to manually break the loop **/while (i++ < n) sum += parseFloat(prompt(`Enter a number (${i} remaining) :`, 0));output.textContent = (sum / n).toFixed(2); /** now we know how many numbers entered from the beging thanks to the variable "n" **/

     parseFloat used to parse the numbers (in fact they're strings) entered by the user to floats.

     toFixed is used to have only two decimal numbers when calculating the average.

   • How do you write a java program that generates the first 100 palindromic numbers (starting from 11, 22, etc), with 10 numbers per line

     Top Answer

     Since we're posting code, I'll post mine. I don't think the op will just copy my code, but I hope he'll learn and copy my techniques.

     Here are my test results.

     11 22 33 44 55 66 77 88 99 101 111 121 131 141 151 161 171 181 191 202 212 222 232 242 252 262 272 282 292 303 313 323 333 343 353 363 373 383 393 404 414 424 434 444 454 464 474 484 494 505 515 525 535 545 555 565 575 585 595 606 616 626 636 646 656 666 676 686 696 707 717 727 737 747 757 767 777 787 797 808 818 828 838 848 858 868 878 888 898 909 919 929 939 949 959 969 979 989 999 1,001

     I did exactly what I stated in my comment.

     I created an int array of 100 elements.

     I generated the first 100 palindromic integers.

     I printed the 100 palindromic integers.

     By breaking up the process into steps (methods), I was able to focus on one method at a time. I didn't write all the code before I ran the first test. I probably ran 10 tests or so before the code was complete.

     Here's the complete runnable code.

     import java.text.NumberFormat;-public class PalindromicIntegers { public static void main(String[] args) { new PalindromicIntegers().generatePalindromicIntegers(); } public void generatePalindromicIntegers() { printResults(generatePalindromes()); } private int[] generatePalindromes() { int[] palindromes = new int[100]; int value = 11; int index = 0; while (index < 100) { if (isPalindrome(value)) { palindromes[index++] = value; } value++; } return palindromes; } private void printResults(int[] palindromes) { NumberFormat numberFormat = NumberFormat.getIntegerInstance(); String s = numberFormat.format(palindromes[palindromes.length - 1]); int length = s.length() + 3; String format = "%" + length + "s"; for (int i = 0; i < palindromes.length; i++) { s = numberFormat.format(palindromes[i]); System.out.print(String.format(format, s)); if ((i + 1) % 10 == 0) { System.out.println(); } } } private boolean isPalindrome(int value) { StringBuilder builder = new StringBuilder(); String s = Integer.toString(value); builder.append(s); builder.reverse(); return builder.toString().equals(s); }}

   • How do you write a fortran program to print the sum of all the elements in a square matrix

     Top Answer

     Answered May 21, 2020 · -1 votes

     One way is to use a nested loop in fortran. Let A(1:n1,1:n2) be the array and a general code for any matrix would be,(I'm assuming you have everything declared n1,n2 as integers; sum as real and A as the appropriate array)

     n1 = size(A,1)n2 = size(A,2)sum = 0.0d0do i = 1,n1 do j = 1,n2 sum = sum + A(i,j) enddoenddoprint*, 'Sum of elements in array is',sum

     For a square matrix n1 and n2 is the same number. If saving as .f file, keep in mind fortran77 format when writing the code.

     Edit: Simplest would be, as someone correctly pointed out,

     print*, sum(A)-

   What is an example of an equation?

   • Equations are math statements that tell you two things are equal. For instance, 5 + 3 = 8 is an equation that tells you the values on both sides of the equals sign are the same. If you wrote this equation and left out any of the three numbers, your friend could figure out the missing number, since both sides are equal.

   How do you set up an equation?

   • Setting up an equation is similar to translating a paragraph between two languages. The result should contain the same information as the original piece. A direct translation is not always possible, because words that exist in one language may not exist in another, or a word-for-word translation may not make sense in the final language.
