How to detect the sign of a number?

[Jick]

I have output which gives either negative number or positive number. My problems is how to detect the sign of the number and output boolean value? For example if input number is negative like -23.11 I want to output false and if the number is positive like 17.99 I want to output true.

Test whether the number is larger or equal Zero.

Hi Jick,

Maybe you should look at the Comparison palette.

Things like smaller/greater than 0 and smaller/greater and Equal to 0

There is also a Sign vi, for future reference.  However in this case that check against 0 gives you the boolean directly, and is more useful
