-.Sh NAME
-.Nm erf ,
-.Nm erfc
-.Nd error function operators
-.Sh LIBRARY
-.Lb libm
-.Sh SYNOPSIS
-.In math.h
-.Ft double
-.Fn erf "double x"
-.Ft double
-.Fn erfc "double x"
-.Sh DESCRIPTION
-These functions calculate the error function of
-.Fa x .
-.Pp
-The
-.Fn erf
-calculates the error function of x; where
-.Bd -ragged -offset indent
-.if n \{\
-erf(x) = 2/sqrt(pi)\(**\|integral from 0 to x of exp(\-t\(**t) dt. \}
-.if t \{\
-erf\|(x) :=
-(2/\(sr\(*p)\|\(is\d\s8\z0\s10\u\u\s8x\s10\d\|exp(\-t\u\s82\s10\d)\|dt. \}
-.Ed
-.Pp
-The
-.Fn erfc
-function calculates the complementary error function of
-.Fa x ;
-that is
-.Fn erfc
-subtracts the result of the error function
-.Fn erf x
-from 1.0.
-This is useful, since for large
-.Fa x
-places disappear.

-.Sh HISTORY
-The
-.Fn erf
-and
-.Fn erfc
-functions appeared in
-.Bx 4.3 .
