-.Sh NAME
-.Nm modf ,
-.Nm modff ,
-.Nm modfl
-.Nd extract signed integral and fractional values from floating-point number
-.Sh LIBRARY
-.Lb libm
-.Sh SYNOPSIS
-.In math.h
-.Ft double
-.Fn modf "double value" "double *iptr"
-.Ft float
-.Fn modff "float value" "float *iptr"
-.Ft long double
-.Fn modfl "long double value" "long double *iptr"
-.Sh DESCRIPTION
-The
-.Fn modf ,
-.Fn modff ,
-and
-.Fn modfl
-functions break the argument
-.Fa value
-into integral and fractional parts, each of which has the
-same sign as the argument.
-It stores the integral part as a
-floating point number
-in the object pointed to by
-.Fa iptr .
-.Sh RETURN VALUES
-These functions return the signed fractional part of
-.Fa value .

-.Xr math 3
-.Sh STANDARDS
-The
-.Fn modf ,
-.Fn modff ,
-and
