Use the fast-exponentiation method to raise x
to the power y
with respect to the modulus
modulus
. The optional
scale
can be used to set the number of
digits after the decimal place in the result.
Замечание: Because this method uses the modulus operation, non-natural numbers may give unexpected results. A natural number is any positive non-zero integer.
The following two statements are functionally identical. The bcpowmod() version however, executes in less time and can accept larger parameters.
