round()

Syntax

round(source [, Precision])

Arguments

• source: The source scalar the round is calculated on.
• Precision: Number of digits the source will be rounded to.(default value is 0)

Returns

The rounded source to the specified precision.

Round is different than bin()/floor() in that the first rounds a number to a specific number of digits while the last rounds value to an integer multiple of a given bin size (round(2.15, 1) returns 2.2 while bin(2.15, 1) returns 2).

Examples

round(2.15, 1)                   // 2.2
round(2.15) (which is the same as round(2.15, 0))                   // 2
round(-50.55, -2)                   // -100
round(21.5, -1)                   // 20
