Pixel Math - evaluate the value of a specific pixel

Jerald Kamienski
in PixInsight
I am a Pixel Math beginner, thus any guidance provided should take this fact into consideration

Toward the end of the first Fundamentals Pixel Math Adam provided a formula  that would evaluate the specific value of a pixel.

Example:  Iff(x() == .001247, 0. $T)

Parse returns the following error:  Unknown function identifier:

Can someone point out what the error is telling me.

Thanks

    It is a silly error I always make.
    The function is "iif" not "iff"

    that is i i f    not i f f   just to be clear. 
    Sorry!

     Thanks Blockhead,

    "iff"was the issue, it was staring me right in the face. Now even the error message makes complete sense.

    Thanks
