Template documentationThis template may be used to enclose text between two parentheses. It adds padding (of width 0.1 em) on each side inside the parentheses.
Usage
{{Pars|<s=200%>|<Content-inside-parentheses>}}
- Places
( )around the content: (Content-inside-parentheses) - Scales their size to 200%
- You can also use the units px, em, pt, or %
- Adds small spaces immediately after ( and immediately before )
Parameters
This template has the following parameters
|1=(positional parameter) - the text that goes inside of the parentheses.|s=or|2=- "s" stands for "size". size=SIZE（px, em, pt, or %. If|s=100%then the size of the parentheses is not changed (i.e. the parentheses have their usual size). If|s=200%(resp.|s=50%) then the parentheses are twice (resp. half) their usual size.- You may use the positional parameter 2 instead of s (e.g. you may use
{{Pars|<text>|<50%>}}in place of{{Pars|<text>|<s=50%>}}). - If neither the parameter s nor 2 is assigned a value then the size of the parentheses is not changed (i.e. the parentheses have their usual size) and no call to the
{{font}}template is made.
- You may use the positional parameter 2 instead of s (e.g. you may use
Examples
No arguments passed
This call {{math|{{pars}}}} produces parentheses.This call ( ) produces parentheses.
No resizing used and content is passed
If {{math|{{pars|X}} < 0}}, then {{mvar|X}} is negative.If (X) < 0, then X is negative.
Parentheses are resized and no content passed
If {{math|{{pars|2=210%}} < 0}}, then {{mvar|X}} is negative.If ( ) < 0, then X is negative.
If {{math|{{pars|s=210%}} < 0}}, then {{mvar|X}} is negative.If ( ) < 0, then X is negative.
Content is resized but parentheses aren't
If {{math|{{pars|{{large|X}}}} < 0}}, then {{mvar|X}} is negative.If (X) < 0, then X is negative.
Parentheses are resized but content isn't
If {{math|{{pars|X|210%}} < 0}}, then {{mvar|X}} is negative.If (X) < 0, then X is negative.
If {{math|{{pars|X|s=210%}} < 0}}, then {{mvar|X}} is negative.If (X) < 0, then X is negative.
Content and parentheses are resized. Using parameter s for size of parentheses
If {{math|{{pars|{{large|X}}|s=210%}} < 0}}, then {{mvar|X}} is negative.If (X) < 0, then X is negative.
Content and parentheses are resized. Passing arguments by their position
Here we indicate the size of the parentheses (as a percentage) by using parameter position number 2 rather than the named parameter |s=.
If {{math|{{pars|{{large|X}}|210%}} < 0}}, then {{mvar|X}} is negative.If (X) < 0, then X is negative.
This is equivalent to the following two lines:
If {{math|{{pars|1={{large|X}}|2=210%}} < 0}}, then {{mvar|X}} is negative.If (X) < 0, then X is negative.
If {{math|{{pars|{{large|X}}|2=210%}} < 0}}, then {{mvar|X}} is negative.If (X) < 0, then X is negative.
WARNING: in the following line, 1 is first set to {{large|X}} and then because "210" is the first unlabelled positional argument, the value of 1 is overwritten and replaced by "210" (which is why 210 appears inside the parentheses) while the positional argument 2 is never assigned a value (which is why the parentheses have their usual size). This is a documented quirk of Wikipedia templates that could occur with many templates that take two or more arguments.
If {{math|{{pars|1={{large|X}}|210%}} < 0}}, then {{mvar|X}} is negative.If (210%) < 0, then X is negative.
WARNING: the following is NOT valid since it would attempt to place the text "210" inside the parentheses (this is because the positional parameter 1 is assigned the value 210) and then attempt to pass X as the percentage number to the template {{font}} (this is because the positional parameter 2 is assigned the value {{large|X}}) even though it is not a valid number.
If {{math|{{pars|210%|{{large|X}}}} < 0}}, then {{mvar|X}} is negative.It results in the following ill-formed output:
- If <span style="font-family:sans-serif;font-size:X;color:black;background-color:transparent;;">(210%<span style="font-family:sans-serif;font-size:X;color:black;background-color:transparent;;">) < 0, then X is negative.
