Function

RoundDown(value)

 value

RoundDown(value, digits)

 value digits

RoundDown is included by default in each file as part of the Math library.

##### Use

The RoundDown() function returns a number rounded down to a given decimal point. If nothing is provided for the decimal point, 0 is assumed.

The number result given by RoundDown() is a new number stored at that value, as opposed to rounding with value formatting, which only changes how a number is displayed.

RoundDown() treats rounding down as rounding towards 0. For example, `RoundDown(-7.8)  = -7`.

##### Units

Numbers with units will be rounded based on those units. This means that the unit a number has at the point of calculation will affect the answer.

For example, `RoundDown(5.8ft)` and `RoundDown(5.8 ft to mm)` will return values that are not equal.

##### Examples
• `RoundDown(1.8)  = 1`
• `RoundDown(1.2)  = 1`
• `RoundDown(-1.8)  = -1`
• `RoundDown(1.8888, 2)  = 1.88`
• `RoundDown(1.8888, 3)  = 1.888`
• `RoundDown(45183.1, -2)  = 45100`
• `RoundDown(3.2 ft)  = 3ft`
• `RoundDown(3.2 ft to cm)  = 97cm`
• `RoundDown(3.2 ft to cm) to ft  = 3.182 ft`
