NAME
     copysign, copysignf, finite, finitef, ilogb, ilogbf, nextafter,
     nextafterf, remainder, remainderf, scalbn, scalbnf - functions for IEEE
     arithmetic

LIBRARY
     libm

SYNOPSIS
     #include <math.h>

     double
     copysign(double x, double y);

     float
     copysignf(float x, float y);

     int
     finite(double x);

     int
     finitef(float x);

     int
     ilogb(double x);

     int
     ilogbf(float x);

     double
     nextafter(double x, double y);

     float
     nextafterf(float x, float y);

     double
     remainder(double x, double y);

     float
     remainderf(float x, float y);

     double
     scalbn(double x, int n);

     float
     scalbnf(float x, int n);

DESCRIPTION
     These functions are required or recommended by IEEE Std 754-1985.

     copysign() returns x with its sign changed to y's.

     finite() returns the value 1 just when -Infinity < x < +Infinity; other-
     wise a zero is returned (when |x| = Infinity or x is NaN).

     ilogb() returns x's exponent n, in integer format. ilogb(+-Infinity) re-
     turns INT_MAX and ilogb(0) returns INT_MIN.

     nextafter() returns the next machine representable number from x in
     direction y.

     remainder() returns the remainder r := x - n*y where n is the integer
     nearest the exact value of x/y; moreover if |n - x/y| = 1/2 then n is
     even. Consequently the remainder is computed exactly and |r| <= |y|/2.
     But remainder(x, 0) and remainder(Infinity, 0) are invalid operations
     that produce a NaN.

     scalbn() returns x*(2**n) computed by exponent manipulation.
