-FUNCTION
- <<cpow>>, <<cpowf>>---complex power
-
-INDEX
- cpow
-INDEX
- cpowf
-
-ANSI_SYNOPSIS
- #include <complex.h>
- double complex cpow(double complex <[x]>, double complex <[y]>);
- float complex cpowf(float complex <[x]>, float complex <[y]>);
-
-
-DESCRIPTION
- @ifnottex
- The cpow functions compute the complex power function x^y
- power, with a branch cut for the first parameter along the
- negative real axis.
- @end ifnottex
- @tex
- The cpow functions compute the complex power function $x^y$
- power, with a branch cut for the first parameter along the
- negative real axis.
- @end tex
-
- <<cpowf>> is identical to <<cpow>>, except that it performs
- its calculations on <<floats complex>>.
-
-RETURNS
- The cpow functions return the complex power function value.
-
-PORTABILITY
- <<cpow>> and <<cpowf>> are ISO C99
-
-QUICKREF
- <<cpow>> and <<cpowf>> are ISO C99
