floor - Rounding a value down to the nearest whole number

Description

floor(number)

Arguments

Return Type

Returns a whole number that is less than or equal to the given numeric value.

floor(-3.2) = -4

Notes

• floor is useful when numbers need to be consistently rounded down in formulas, for example, when calculating costs or other values where decimal places need to be removed.
• For negative numbers, it also rounds down, so the resulting value is further away from zero (e.g., floor(-2.8) results in -3).
