Python: pow() function

pow() function

The pow() function is used to get the value of x to the power of y (xy). If z is present, return x to the power y, modulo z (computed more efficiently than pow(x, y) % z).

Version:

(Python 3.2.5)

Syntax:

pow(x, y[, z])

Parameter:

Name Description Required /
Optional
x A number (the base) which is to be powered. Required
y A number (the exponent) which is to be powered with x. Required
z A number which is to be used for modulus operation. Optional

Example: Python pow() function

# positive a, positive b (a**b)
print(pow(4, 4))

# negative a, positive b
print(pow(-4, 4))

# positive a, negative b (a**-b)
print(pow(4, -4))

# negative a, negative b
print(pow(-4, -4))

Output:

256
256
0.00390625
0.00390625
