Question

Is it possible to calculate the value of the mathematical constant, e with high precision (2000+ decimal places) using Python?

I am particularly interested in a solution either in or that integrates with NumPy or SciPy.

Answer 1

You can set the precision you want with the decimal built-in module:

from decimal import *
getcontext().prec = 40
Decimal(1).exp()

This returns:

Decimal('2.718281828459045235360287471352662497757')
