a b 137 137 * ``3`` becomes ``3rd``. 138 138 139 139 You can pass in either an integer or a string representation of an integer. 140 141 .. templatefilter:: percentage 142 143 percentage 144  145 146 Converts a number to a percentage. 147 Takes an optional integer argument for decimal point accuracy. 148 149 Examples: 150 151 * ``1.5`` becomes ``150.00%``. 152 * ``Fraction(1)/2`` becomes ``50.00%``. 153 * ``Decimal(1) / Decimal(2)`` becomes ``50.00%``. 154 * ``not a number`` returns ``not a number``. 155 156 You can pass in either an integer or a string representation of a number. 157 **Argument:** Decimal precision can be set utilizing the precision optional argument. 158 Any number type can be passed, but the function will convert to an integer, 159 following Python's conversion rules. 160 161 For example:: 162 163 {{ valuepercentage:3}} 164 165 * ``1.5`` becomes ``150.000%``. 166 167 168 Default precision is set to 2. 169 No newline at end of file
