 These functions truncate x to an integer (discarding the fractional part).
 
+There are also added functions that correspond to existing <math.h> functions, but using float or long double for their argument and return types.  In ORCA/C, most of these actually behave identically to the existing un-suffixed versions.  An exception is the modf family of functions, which differ in the type of the location in which the integer part of the value is stored.
