Round Floats To Integers
The Float.round/2
function allows you to round floating point numbers. The result is another floating point number.
> Float.round(1.5)
2.0
> Float.round(1.3)
1.0
If, instead, you always want an integer as the result of rounding, you can use Kernel
's version of a rounding function:
> Kernel.round(1.5)
2
> Kernel.round(1.3)
1
The Kernel.round/1
function accepts both integers and floats, and always returns an integer. Additionally, it can be used in guard tests.
