A float is a very basic thing, if you're atleast 12 years old you should have learned it at school already, lol.

A float (%f) is examply 5.05858 (can contain non-round numbers / decimals)
An integer/decimal (%i / %d) is examply 5 (cannot contain non-round numbers / decimals)

Floats are examply used for coordinates, health (sa-mp), armour(sa-mp) ..
