Computes the base X logarithm of a specified input value.

(x>0, y>0). If y is 0, the output is - . When x and y are both non-complex and x is less than or equal to 0, or y is less than 0, the output is not a number (NaN).

logx(y)

Logarithm of y to the base x.

When x and y are complex, the following equation defines logx(y):
log x ( y ) = ln ( y ) ln ( x )
