I have a problem in a sum in JavaScript, example 188/100 = 1.88 * 100 = 188, but I do not want it to reach 188, I want the number to always reach number 100.

188/100 * 100 = 100

Personally I've got it simple!

i = 50; 
100/i*i;

If you want a number that multiplied by 188 give 100 as a result, just do:

fator = 100/188; // Perceba que usei 100/188 e não 188/100

cem = fator * 188; // Vai dar 100 (com algum possível problema de arredondamento)

Change the comma by period. In Javascript, the decimal separator is the dot;)

i.e.:

1,88 * 100 // 8800

This is because the interpreter sees this as:

1;
88 * 100;

The code below is getting closer than you want:

1.88 * 100; // 188;

Another thing. If you want to divide a number into 100 equal parts, continue with that reasoning. If you want a number to reach 100 in exactly 100 addition iterations, then start from 0 and increase until you reach 100. The most classic form, and the first arcane phrase that most programmers learn, is the following: / p>

for (var i = 0; i < 100; i++)
