Python math - erfc() Function

The Python math.erfc() function returns the complementary error function of the argument. The complementary error function of x is defined as:

Where, erf(x) is an error function. Error functions usually occur in probability, statistics and partial differential equation describing diffusion.

Syntax

math.erfc(x)   

Parameters

Return Value

Returns the complementary error function of the argument.

Example:

In the example below, erfc() function returns the complementary error function of the given value.

import math

print(math.erfc(0))
print(math.erfc(1))
print(math.erfc(2),"\n")

print(math.erfc(-0.1))
print(math.erfc(-1))
print(math.erfc(-2))

The output of the above code will be:
