ਫਰਮਾ:Pars( ) Usage
This template may be used to enclose text between two parentheses. It adds padding (of width 0.1 em) on each side inside the parentheses. This template has the following parameters
Examples
This call {{math|{{pars}}}} produces parentheses.
If {{math|{{pars|X}} < 0}}, then {{mvar|X}} is negative.
If {{math|{{pars|2=210%}} < 0}}, then {{mvar|X}} is negative.
If {{math|{{pars|s=210%}} < 0}}, then {{mvar|X}} is negative.
If {{math|{{pars|{{large|X}}}} < 0}}, then {{mvar|X}} is negative.
If {{math|{{pars|2=210%|X}} < 0}}, then {{mvar|X}} is negative.
If {{math|{{pars|s=210%|X}} < 0}}, then {{mvar|X}} is negative.
"s" stands for "size". It indicates the new size of the parentheses relative to their usual size (e.g. s=200 produces parentheses with twice their usual size, s=100 produces the usual size, etc.). If {{math|{{pars|s=210%|{{large|X}}}} < 0}}, then {{mvar|X}} is negative.
Here we indicate the size of the parentheses (as a percentage) by using parameter number 2 rather than the named parameter s. If {{math|{{pars|2=210%|{{large|X}}}} < 0}}, then {{mvar|X}} is negative.
If {{math|{{pars|2=210%|1={{large|X}}}} < 0}}, then {{mvar|X}} is negative.
Both of the above lines produce identical output, which is:
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.
This is equivalent to the following two lines: If {{math|{{pars|1={{large|X}}|2=210%}} < 0}}, then {{mvar|X}} is negative.
If {{math|{{pars|{{large|X}}|2=210%}} < 0}}, then {{mvar|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.
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:
