Template:Rounddown

Template:Rounddown

This template rounds a numeric expression down to a given number of decimal places. Down in the sense that e.g. -2.5 is rounded to -3. Compare Template:Roundtozero.

Usage:

{{Rounddown|expression}}

{{Rounddown|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:

{{Rounddown|3.14159|3}} = 3.141

{{Rounddown|-3.14159|3}} = -3.142

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

{{Rounddown|-314159|-3}} = -315000

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

{{Rounddown|2<1}} = 0

{{Rounddown|-1/3}} = -1

{{Rounddown|-2/3}} = -1

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

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

{{Rounddown|3<=4}} =
