Library FunctionsMODFSynopsis#include double modf (double value, double * iptr)DescriptionThe modf() function splits the argument value into integral and fractional parts, each having thesame sign as value. For example, -3.17 would be split into the intergral part (-3) and the fractionalpart (-0.17).The integral part is stored as a double in the object pointed to by iptr.Example#include #include voidmain (void){double i_val, f_val;}f_val = modf( -3.17, &i_val);Return ValueThe signed fractional part of value.172
