cpow-Complex Power

Interface

F_COMPLEX cpow (F_TYPE a, F_TYPE b, F_TYPE c, F_TYPE d)

Description

cpow() raises a complex base (a + ib) to a complex exponent (c + id).

cpow(a,b,c,d) is defined as e**((c + id) ln(a + ib)).

Exceptions

Exceptional Argument                      Routine Behavior

sqrt (a**2 + b**2) > max_float            Overflow

c/2 * ln(a**2 + b**2) > max_float         Overflow

c/2 * ln(a**2 + b**2) - (d * atan2(b,c))  Overflow
> max_float
