Infinity is a mathematical concept but it needed to be incorporated into computing. Hence, infinity consists in a special single or double value which is created whenever necessary.

Infinity is defined by the IEEE floating-point standard on Wikipedia.

[edit] Infinity in REALbasic

Infinity can be either positive or negative.

dim positiveInfinity, negativeInfinity as double

positiveInfinity = 1.0 / 0.0
negativeInfinity = -1.0 / 0.0

// Str( positiveInfinity ) returns "INF"
// Str( negativeInfinity ) returns "-INF"

You can also create an infinite number with:

dim myInfiniteNumber as double = Val( "INF" )
