trunc

Details #

trunc(number) takes exactly one argument and returns the whole number nearest to zero: it cuts off the decimals. trunc(2.9) is 2 and trunc(-2.9) is -2.

floor differs for negatives (floor(-2.9) is -3), and round goes to the nearest whole number.

Parameters #

Takes 1 argument. {{ trunc(text) }}

Examples #

trunc(2.9)

trunc(-2.9)

trunc(price * 100) / 100

Gotchas #

• Calling it with no argument or two arguments is an error: trunc() takes 1 argument, got 2.

• Anything that isn't a number is an error: trunc() needs a number, got text. Numeric text such as "0.5" is accepted.
