ERFC(x)

• $x$ is the lower limit.

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:

$ERFC(x)={\frac {2}{\sqrt {\pi }}}\int \limits _{x}^{\infty }e^{-t^{2}}dt=1-ERF(x)$.

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

Examples

1. ERFC(3)=0.0000219610
2. ERFC(2)=0.0046777624247
3. ERFC(0)=1
4. ERFC(-2)=NAN
