lngamma(PythonObject) -- natural logarithm of the gamma function of a python object

Function: lngamma
Usage:

lngamma x
Inputs:
- x, a python object,
Outputs:
- a python object,

Description

This calls Python's built-in math.lgamma function, which computes the natural logarithm of the gamma function of x.

i1 : lngamma toPython 5

o1 = 3.178053830347945

o1 : PythonObject of class float

i2 : log Gamma toPython 5

o2 = 3.1780538303479458
