ERFC(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:
.
- This function will return the result as error when x is nonnumeric or negative.
Examples
- ERFC(3)=0.0000219610
- ERFC(2)=0.0046777624247
- ERFC(0)=1
- ERFC(-2)=NAN
