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(glossary)|returns> 5, but floor(4.99) <return(glossary)|returns> 4. This means that the <floor> function does not always <return(constant)> the <integer> closest to the <number>.
