RoundDown(value) value RoundDown(value, digits) value digits

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
