Obsolete IDL Features: Obsolete Routines

ERRORF

This routine is obsolete and should not be used in new IDL code.

The ERRORF function returns the value of the error function:

The result is double-precision if the argument is double-precision. If the argument is floating-point, the result is floating-point. The result always has the same structure as X. The ERRORF function does not work with complex arguments.

Syntax

Result = ERRORF(X)

Arguments

X

The expression for which the error function is to be evaluated.

Example

To find the error function of 0.4 and print the result, enter:

PRINT, ERRORF(0.4)  

IDL prints:

0.428392
