How to compare a sign

[bknight]

Suppose I have a record that contains a +1, how do I put an if statement that looks for n<0, conversely if the record contained a -1 the if statement would search for n>0. Both instances need to be evaluated in the if statement because the original value is either a + or -.

Never 0?
Use a nested IIF() perhaps?

Never a zero, that is correct.
I'm not sure how to structure a nested f for all/both conditions.
