ERFC(a,accuracy)

$a$ is the lower limit.

- ERFC(),returns the Complementary Error Function

Description

This function gives the complementary ERF function.
The complementary error function is the error function with the limit x and infinity. It is denoted by erfc(x).
It is also called scaled complementary error function.
ERFC is defined by:

Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle ERFC(x)=\frac{2}{\sqrt{\pi}}\int\limits_{x}^{\infty}e^{-t^2} dt=1-ERF(x)} .

This function will return the result as error when a is nonnumeric or negative.
