What does suffix 'f' mean in Java code?

Question

Here\'s the explanatory code. The language is Java and the code uses Android.

fg.setTextSize(height*0.50f); //<-\'f\' is in the brackets

Answer 1

It indicates 3 is float not integer in other case 0.50 is float not double. Just like in any other java program.

Answer 2

It's a float, not a double. This is basic Java (C) notation.

Answer 3

float ;)

it's a 3 that is a float, not an int

Answer 4

You don't need to append the f if entering 0 or 1 or during certain assignments. But other times you do need it especially when the compiler can't tell if its a float or a double or an int or needs to cast the value in some way. It's maddeningly inconsistent really.

Answer 5

It indicates a float literal.
