Recap of Floating Point Numbers
What We’ve Covered So Far
Floating point number variables (also called floats) are used when you need a number with a decimal point in it.
Declaring a float variable:
float moo; // declaring a float variable named foo
Changing a float variable:
moo = 21.3;
Declaring and assigning a float variable at the same time:
float moo = 0.955; // declaring a float named moo with a value of zero point nine five five
Doing math with a float variable is just like doing regular math with a variable in Algebra.
Sometimes float variables create what a rounding error, so use integers whenever you can.

You will often need to work with more than numbers. Sometimes you need to write text. For that, you will need to learn about characters:
