erf

Evaluates the real error function.

Prototype

	function erf (
		x : numeric [float or double] 
	)
	return_val : same size/shape/type as x

A scalar or multi-dimensional array of type float or double.

Same size as x. The return value is double if x is double, and float otherwise.

Evaluates the real error function.

Example 1

 x = (/ 0, 100, 0.8, -0.8, 0.1/)
 result = erf (x)
 print ("x="+x+" xresult="+result)

The results are:

 x= 0 xresult= 0
 x= 100 xresult= 1
 x= 0.8 xresult= 0.742101
 x=-0.8 xresult=-0.742101
 x= 0.1 xresult= 0.112463
