Usage
{{percentage|numerator|denominator|decimals to round to (zero or greater)}}
Limitations
Figures smaller than 0.0001% are shown in scientific notation.
Examples
{{Percentage | 1 | 3 | 0 }}yields 33%{{Percentage | 1 | 3 | 2 }}yields 33.33%
Negative values can be used:
{{Percentage | -1 | 3 }}yields -33%
Normal operation is to cut off all decimal zeroes from right in rounding:
{{Percentage | 1 | 5 | 2 }}yields 20%{{Percentage | 1111 | 10000 | 4 }}yields 11.11%
Add |pad=yes to always get as many decimals as specified, padding with zeroes where needed:
{{Percentage | 1 | 5 | 2 | pad=yes }}yields 20.00%{{Percentage | 1111 | 10000 | 4 | pad=yes }}yields 11.1100%
Third parameter can also be given through |pad=N:
{{Percentage | 111 | 1000 | pad=4 }}is same as{{Percentage | 111 | 1000 | 4 | pad=yes }}and yields 11.1000%
Default denominator is 100:
{{Percentage | 20 }}yields 20%
Default precision is zero:
{{Percentage | 1 | 3 }}yields 33%
Override the percent symbol
{{Percentage | 1 | 3 | % = percent}}yields 33 percent
Use a prescribed number of significant figures
{{Percentage | 1 | 4000 | sigfig = 3}}yields 0%
Use a prescribed number of significant figures with small percentages
{{Percentage | 1 | 40000000 | sigfig = 3}}yields 0%
Use a prescribed number of significant figures with small percentages without scientific notation
{{Percentage | 1 | 40000000 | sigfig = 3 | nonscinote = y}}yields 0%
Use a prescribed number of significant figures with large percentages
{{Percentage | 40000000 | 2 | sigfig = 3}}yields 2000000000%
Use a prescribed number of significant figures with large percentages without scientific notation
{{Percentage | 40000000 | 2 | sigfig = 3 | nonscinote = y}}yields 2000000000%
Dividing by zero will result in "nan" (undefined)
{{Percentage | 0 | 0 | 0 }}yields Expression error: Division by zero%
TemplateData
TemplateData for Percentage
Calculates and displays a percentage value.
| Parameter | Description | Type | Status | |
|---|---|---|---|---|
| Numerator | 1 | The Numerator of the calculated value. The percentage will be calculated as Numerator divided by Denominator. Use of comma as a thousands separator is optional. | Number | required |
| Denominator | 2 | The Denominator of the calculated value. The percentage will be calculated as Numerator divided by Denominator. Use of comma as a thousands separator is optional. Can be left out, in which case 100 will be used as the Denominator, and the Numerator will be the direct percentage used.
| Number | suggested |
| Decimals | 3 | Number of decimals to round to (zero or greater); if pad is not Yes, 0-digits will be cropped from the end.
| Number | optional |
| Pad / actual number of digits | pad | If yes, use all digits given in Decimals. If a number, pad to that number of decimals. | String | optional |
| Significant figures | sigfig | If set to a positive integer, the precision of the returned number will be adjusted to match the requested number of significant figures. | Number | optional |
| % replacement | % | Replacement for % symbol
| String | optional |
