A question of the syntax

[zhang-yu]

I want to ask you a question of maya mel.I found a word "#INF" here

float $dotProduct = 0, $lastDotProd = -1.#INF; // <- maya syntax for negative infinity..."

what's the #INF meaning? And how it can be used in python?

Is there anybody can tell me about much more  infomation about  syntax like the #INF
Thanx!
