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

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