How to stop truncation in JavaScript number division

In Java we use the double or float data type to get results in decimal points. However how do i do this in Javascript? The current calculation i am doing is:

a1 += (a1 *  results[0][index]) / 100;

EDIT, My Apologises, There was a mistake on my side from using the wrong variables.

All numbers in JavaScript are like Java "double" values. The general problem one encounters in JavaScript is how to do math as if they're not floating-point.

Thus in an expression like yours, if the numerator is not evenly divisible by 100 you'll get a value with a fractional part. You can use "Math.round()" or "Math.floor()" to round or truncate the fraction, but you'll definitely get it.
