Method

Xojo.Math.Floor() As Double

Supported for all project types and targets.

Returns the value rounded down to the nearest whole number.

Sample Code

The floor of a decimal number:

Using Xojo.Math

Dim d As Double
d = Floor(1.234) // d = 1

Because Floor will always return a whole number, to round a decimal value to a certain number of places, you must first multiple the number by 10^(the number of decimal places to which you wish to round) then take the value returned by Floor of that number and divide it by 10^(the number of decimal places to which you wish to round). In this example, the value 1.2345 is being rounded to two decimal places:

Dim d As Double
d = Xojo.Math.Floor(1.234 * 100) / 100
