Definition and Usage

The math.gamma() method returns the gamma value of a number.

The gamma value is equal to factorial(x-1).

Tip: To find the log gamma value of a number, use the math.lgamma() method.

Syntax

math.gamma(x)

Parameter Values

Parameter Description
x Required. The number to find the gamma value of. If the number is a negative integer, it returns a ValueError. If it is not a number, it returns a TypeError.

Technical Details

Return Value: A float value, representing the gamma value of a number
Python Version: 2.7
