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

Alternatively you could use the function you were already using.

float_to_list(0.02,[{decimals, 2}]) outputs '0.02'

Or for Elixir users ;)

:erlang.float_to_list(5.231,[{:decimals, 2}]) outputs '5.2'
