Xf notation vs just a number?

Whhat does the f label signify when a number has a f appended to it - for example `var x=10f;` - how is that different than `var x=10`?

sorry for the elementary question, but if the variable is declared as a float, is it redundant to add the f?

Hi,

This is basically to say that it is a float.
