I need help, I am a new to the IDL.

Does the IDl have something close to Fortran SIGN (DSIGN... so on...)
functions

IN FORTRAN:
Elemental Intrinsic Function (Generic):
Returns the absolute value of the first argument times the sign of the
second argument.

Syntax:
=======
result = SIGN (a, b)
a (Input) Must be of type integer or real.

b Must have the same type and kind parameters as a.

Results:
=========
The result type is the same as a.
The value of the result is
| a | if b >= zero
and -| a | if b < zero.

--

Best regards, and thank you in advance
