テンプレート:Roundtozero

This template rounds towards zero (aka truncates) a numeric expression to a limited number of decimal places.

Usage:

{{Roundtozero|expression}}

{{Roundtozero|expression|decimals}}

Both parameters can be any valid numeric expression.

The decimals parameter defaults to 0 and is rounded to the nearest integer.

decimals can be negative to round down to a multiple of a power of ten.

Examples:

{{Roundtozero|3.14159|3}} = 3.141

{{Roundtozero|-3.14159|3}} = -3.141

{{Roundtozero|314159|-3}} = 314000

{{Roundtozero|-314159|-3}} = -314000

{{Roundtozero|+1/3}} = 0

{{Roundtozero|2<1}} = 0

{{Roundtozero|-1/3}} = 0

{{Roundtozero|-2/3}} = 0

For expressions containing equal signs use 1=expression - the second example fails:

{{Roundtozero|1=3<=4}} = 1

{{Roundtozero|3<=4}} =
