Re: seperating a decimal

One option is something like:

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

Re: seperating a decimal

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