Template:Rounddown

Template documentation[view] [edit] [history] [purge]

This template rounds down a numeric value to a limited number of decimal places.

Usage

• {{Rounddown|value}}
• {{Rounddown|value|decimals}}
• Both parameters can be any valid numeric expression; however, decimals should be an integer.
• The decimals parameter defaults to 0.
• decimals can be negative to round down to a multiple of a power of ten.
• NAN may be returned if very large values are used.

Examples

Template	Result	Expected
{{Rounddown|3.14159|3}}	{{SAFESUBST: #expr:floor((3.14159)*10^(3))/10^(3)}}	3.141
{{Rounddown|0.123|3}}	{{SAFESUBST: #expr:floor((0.123)*10^(3))/10^(3)}}	0.123
{{Rounddown|0.00032|3}}	{{SAFESUBST: #expr:floor((0.00032)*10^(3))/10^(3)}}	0
{{Rounddown|-0.123|3}}	{{SAFESUBST: #expr:floor((-0.123)*10^(3))/10^(3)}}	-0.123
{{Rounddown|-3.14159|3}}	{{SAFESUBST: #expr:floor((-3.14159)*10^(3))/10^(3)}}	-3.142

{{Rounddown|0|0}}	{{SAFESUBST: #expr:floor((0)*10^(0))/10^(0)}}	0
{{Rounddown|-0.31415|0}}	{{SAFESUBST: #expr:floor((-0.31415)*10^(0))/10^(0)}}	-1
{{Rounddown|314159|-3}}	{{SAFESUBST: #expr:floor((314159)*10^(-3))/10^(-3)}}	314000
{{Rounddown|314.15|-3}}	{{SAFESUBST: #expr:floor((314.15)*10^(-3))/10^(-3)}}	0
{{Rounddown|-314159|-3}}	{{SAFESUBST: #expr:floor((-314159)*10^(-3))/10^(-3)}}	-315000
{{Rounddown|.875}}	{{SAFESUBST: #expr:floor((.875)*10^(0))/10^(0)}}	0

Note

• You should use the parserfunction {{#expr:floor value}} rather than {{Rounddown|value}} or {{Rounddown|value|0}}. This template should only be used when rounding down to some number of decimal places other than zero.
