-FUNCTION
-<<copysign>>, <<copysignf>>---sign of <[y]>, magnitude of <[x]>
-
-INDEX
- copysign
-INDEX
- copysignf
-
-ANSI_SYNOPSIS
- #include <math.h>
- double copysign (double <[x]>, double <[y]>);
- float copysignf (float <[x]>, float <[y]>);
-
-TRAD_SYNOPSIS
- #include <math.h>
- double copysign (<[x]>, <[y]>)
- double <[x]>;
- double <[y]>;
-
- float copysignf (<[x]>, <[y]>)
- float <[x]>;
- float <[y]>;
-
-DESCRIPTION
-<<copysign>> constructs a number with the magnitude (absolute value)
-of its first argument, <[x]>, and the sign of its second argument,
-<[y]>.
-
-<<copysignf>> does the same thing; the two functions differ only in
-the type of their arguments and result.
-
-RETURNS
-<<copysign>> returns a <<double>> with the magnitude of
-<[x]> and the sign of <[y]>.
-<<copysignf>> returns a <<float>> with the magnitude of
-<[x]> and the sign of <[y]>.
-
-PORTABILITY
-<<copysign>> is not required by either ANSI C or the System V Interface
-Definition (Issue 2).
