numpy.emath.power#

emath.power(x,p)[source]#

Return x to the power p, (x**p).

Ifx contains negative values, the output is converted to thecomplex domain.

Parameters:

xarray_like

The input value(s).

parray_like of ints

The power(s) to whichx is raised. Ifx contains multiple values,p has to either be a scalar, or contain the same number of valuesasx. In the latter case, the result isx[0]**p[0],x[1]**p[1],....

Returns:

outndarray or scalar

The result ofx**p. Ifx andp are scalars, so isout,otherwise an array is returned.
