Truncate a float in Erlang

Question

I am using a function to create a list from a float.

 float_to_list(0.02).

It returns:

\"2.00000000000000000000e-002\"
         


        

Answer 1

This link provides functions that truncate/floor or ceil or round a float. Given those you can round to 2 digits by multiplying by 100, rounging and then dividing back by 100 (and possibly rounding again to avoid precision errors)
