How would one seperate a decimal into 2 numbers, the left and right sides of the decimal?

float example = 131.14567

into...

int left = 131
float right = .14567

thanks.

One option is something like:

c Syntax (Toggle Plain Text) 
  1.   float in = 131.14567f;
  2.   int left = (int)in;
  3.   float right = left - in;

Or may be convert the double into string. Then split the string using "." as the delimiter??
