INF means "Infinity". It is a "state" that can be stored
(along with "Negative Infinity" and "Not a Number")
in floating point values.

You should avoid using them in IB/FB, because these values
are not sometimes handled correctly and can lead to server crash.

(I never know whether in text I should use IB or FB or IB/FB.
It's like he/she problem :-)
