-.SH DESCRIPTION
-These functions return the error function of
-.IR x ,
-defined as
-.P
-.in +4n
-.EX
-erf(x) = 2/sqrt(pi) * integral from 0 to x of exp(\-t*t) dt
-.EE
-.in
-.SH RETURN VALUE
-On success, these functions return the value of the error function of
-.IR x ,
-a value in the range [\-1,\ 1].
-.P
-If
-.I x
-is a NaN, a NaN is returned.
-.P
-If
-.I x
-is +0 (\-0), +0 (\-0) is returned.
-.P
-If
-.I x
-is positive infinity (negative infinity),
-+1 (\-1) is returned.
-.P
-If
-.I x
-is subnormal,
-a range error occurs,
-and the return value is 2*x/sqrt(pi).
-.SH ERRORS
-See
-.BR math_error (7)
-for information on how to determine whether an error has occurred
-when calling these functions.
-.P
-The following errors can occur:
-.TP
-Range error: result underflow (\fIx\fP is subnormal)
-.\" .I errno
-.\" is set to
-.\" .BR ERANGE .
-An underflow floating-point exception
-.RB ( FE_UNDERFLOW )
-is raised.
-.P
-These functions do not set
-.IR errno .
-.\" It is intentional that these functions do not set errno for this case
-.\" see https://www.sourceware.org/bugzilla/show_bug.cgi?id=6785
