a = -3.1145
your_val = fix(a)
If you also want it to work for negative numbers.

@Rokeya Mumtahana Mou:
If you have a different question , then ask it as a question of your own.
However, there are several functions you should read about.
round: rounds to the nearest integer.
floor: round down toward -inf
fix: round towards zero
ceil: round upwards
You want either ceil or round, depending on the behavior you wish to see. Thus, would 4.49 map to 5, or to 4? ceil would produce always the larger integer, whereas round find the nearest integer.
And of course, fix and floor are identical for positive numbers.
