The math.erf() function is used to calculate the error function for a given input.

The error function (also known as Gauss function or 2nd Gauss function) is an important special function in mathematics and has widespread applications in various scientific fields. It measures the probability that a random variable following a normal distribution lies between two given values.

matgh.erf(x)

Where, parameter x is a real number. If x is not a real number, a TypeError is raised.

The function returns a floating point value which is the value of the error function at x.

import math

print(math.erf(0.01))
print(math.erf(0.5))
print(math.erf(2))
print(math.erf(3.142))
print(math.erf(math.e))
