MIN...MAX and neg. Number

Archiver

Hi
I like to limit the Variable "DegOut" to a min = 1 and max = 410
but my DegOut can be positive and negative.
All numbers smaller 1 should be =1 including the negative numbers

I used this:

DegOut = DegOut MAX 410 MIN 1

but wrong, when DegOut gets negative it gets 410 (65535,limitet to 410)
but I would like to resave a "1"
I tried:

DegOut = ABS DegOut MAX 410 MIN 1

but this just convert the neg. Number to positive numbers
how could I do it ?

Thanks for any help

This ought to keep you going until somebody comes up with something
better:

DegOut = 1 - DegOut.BIT15 * ( DegOut MAX 410 ) + DegOut.BIT15 MIN 1

This solution takes advantage of the fact that a negative value will
have the high order bit set. Works for -32768 <= DegOut < 32768.

Regards,

Steve

Hi Heinz,

I think Steve's solution is very clever! Since there is often more
than one way to do things, here is mine, not necessarily better...
If first offsets your value so that is will be positive, then does
the min and max, and then restores the offset.

degout = degout + 32767 min 32768 max 33177 - 32767

Thanks Steve and Tracy
If I read Your solution it looks so easy now
