Description

$-$ A floating$-$point number consists of a positive or negative sign, a decimal value for the significant digits, and an optional exponent.

$-$ Floating$-$point numbers provide for very large and very small numbers, but with a limited number of significant digits.

$-$ To express the value of a floating$-$point number, you can use scientific notation.

$-$ An integer is an exact value that yields expected results.

$-$ A floating$-$point number is an approximate value that can yield unexpected results known as floating$-$point errors.
