Rounds a number to a whole number or to a number of decimal places.

Keyboard Maestro: round

Details #

round(number, places?) takes one or two arguments and returns a number. Numeric text is accepted.

With one argument it rounds to a whole number. A half rounds away from zero: round(2.5) is 3 and round(-2.5) is -3.
A positive places keeps that many decimals: round(3.14159, 2) is 3.14.
A negative places rounds to tens, hundreds and so on: round(1234, -2) is 1200.

Takes 1 to 2 arguments. {{ round(text, b?) }}

round(2.5)

→ 3

round(3.14159, 2)

→ 3.14

round(1234, -2)

→ 1200

Anything that isn't a number is an error: round() needs a number, got text.
Results are floating point, so round(0.1 + 0.2, 2) is the safe way to get 0.3.
