Yes, might be true. Thats why I asked how many people are using mod
in order to do the operation and truncate the result.
Personally I never used it that way.

man fmod:

DESCRIPTION
       The  fmod()  function  computes  the remainder of dividing x by y.
       The return value is x - n * y, where n is the quotient of x  /  y,
       rounded towards zero to an integer.
