expm1(PythonObject) -- exponential minus one of a python object

Function: expm1
Usage:

expm1 x
Inputs:
- x, a python object,
Outputs:
- a python object,

Description

This calls Python's built-in math.expm1 function, which computes the exponential of x minus one. This is more accurate than computing exp x - 1 for small values of x.

i1 : exp toPython 1e-10 - 1

o1 = 1.000000082740371e-10

o1 : PythonObject of class float

i2 : expm1 toPython 1e-10

o2 = 1.00000000005e-10

o2 : PythonObject of class float
