Parameters:

number:

Any number, or expression that evaluates to a number.

Returns:

The <floor> <function> <return|returns> an <integer>.

Description:

Use the <floor> <function> to return the greatest integer less than or

equal to a number.

The <floor> <function> is different from <round> in that floor

completely ignores the fractional part of the number. For example,

`floor(5.1)` <return|returns> 5, but `floor(4.99)` <return|returns> 4.

This means that the <floor> function does not always <return> the

<integer> closest to the <number>.
