-FUNCTION
- <<sqrt>>, <<sqrtf>>---positive square root
-
-INDEX
- sqrt
-INDEX
- sqrtf
-
-ANSI_SYNOPSIS
- #include <math.h>
- double sqrt(double <[x]>);
- float sqrtf(float <[x]>);
-
-TRAD_SYNOPSIS
- #include <math.h>
- double sqrt(<[x]>);
- float sqrtf(<[x]>);
-
-DESCRIPTION
- <<sqrt>> computes the positive square root of the argument.
- You can modify error handling for this function with
- <<matherr>>.
-
-RETURNS
- On success, the square root is returned. If <[x]> is real and
- positive, then the result is positive. If <[x]> is real and
- negative, the global value <<errno>> is set to <<EDOM>> (domain error).
-
-
-PORTABILITY
- <<sqrt>> is ANSI C. <<sqrtf>> is an extension.
