How to convert float to integer?

Hello,

I have a specific need to convert floats that have only 0 (as fraction) for example :

6.0 => 6
6.2 => I need it to stay float

Thanks

One option:

def maybe_to_int(float) do
  truncated = trunc(float)
  if truncated == float, do: truncated, else: float
end

Basically just convert the float to an integer. If they evaluate as equal then it must have had no decimal part. If they are no longer equal, return the float.

What 1.0 == 1 actually does is convert 1 to 1.0 and compare the same types, which is why it works.
