Definition of Float

A numeric data type that represents fractional values using floating-point precision.

In practice, float becomes easier to use when you trace the input, the state it affects, and the output another part of the program can observe.

A practical example

Use float in a small example first, then vary one input and explain the resulting behavior before you run the code.

What to remember

Remember float as a specific relationship in a program, not as an isolated definition to memorize.
