MODF(3) BSD Library Functions Manual MODF(3)NAME
modf — return integral and fractional parts
modf(double value, double *iptr);
modff(float value, float *iptr);
The modf() and modff() break value into integral and fractional parts,
each of which has the same sign as the argument. They return the frac‐
tional part, and store the integral part (as a floating-point number) in
the object pointed to by iptr
modf(�infinity, iptr) returns �0 and stores �infinity in the object
pointed to by iptr.
modf(NaN, iptr) returns a NaN and stores a NaN in the object pointed to
