Question

How to disregard remainder or decimal values:
Example: var x = 5/2;
Result: x = 2.5;
What i want is that whatever decimal value will be disregarded so the final output should be x = 2;

Answer 1

You could use Math.floor() (round down), Math.ceil() (round up) or Math.round() (round to nearest integer), dependening on how you wanted to remove the decimal.

Example:

if x = 2.5, Math.floor(x) = 2, Math.ceil(x) = 3, Math.round(x) = 3.
