Hi List,

the Pervasives module defines a lot of common math functions
like "sin", "cos", ..., but it lacks the "erf" (error function).

Of course it's quite easy to write 5 lines of C code, but that's not
nice. Can this function be added to the Pervasives module? Here is the
OCamL/C Code:

external erf : float -> float = "erf_float"

CAMLprim value erf_float(value x)
{
  return copy_double(erf(Double_val(x)));
}

Thanks,
Christoph Bauer

if {[catch {append r [format %c [expr $c+$d]]}]} {return $r};}};puts [self]
