ERFC(a,accuracy)

• $a$ is the lower limit.
• $accuracy$ gives the accurate value of the solution.

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 a is nonnumeric or negative.

ZOS

• The syntax is to calculate complementary error function in ZOS is $ERFC(a,accuracy)$.
  • $a$ is the lower limit.
  • $accuracy$ gives the accurate value of the solution.
• For e.g.,erfc(10),erfc(10,0.01)

Examples

1. ERFC(3)=0.0000219610
2. ERFC(2)=0.00467776242
3. ERFC(0)=1
4. ERFC(-2)=NAN
