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 0.0250%

Use a prescribed number of significant figures with small percentages

• {{Percentage | 1 | 40000000 | sigfig = 3}} yields 00%

Use a prescribed number of significant figures with small percentages without scientific notation

• {{Percentage | 1 | 40000000 | sigfig = 3 | nonscinote = y}} yields 00%

Use a prescribed number of significant figures with large percentages

• {{Percentage | 40000000 | 2 | sigfig = 3}} yields 2.00×10⁹%

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 nan%
