Description

The monster.util.formatNumber() method is used to easily format numbers as plain numbers, prices and percentages by applying specific formatting rules set by the locale and/or currency code.

Locale & currency code

The locale set at the framework level is automatically used to format number correctly following its specificities for all style options (currency symbol positioning, grouping separators and fractional digits).

The currency code set at the framework level is automatically used to format number correctly following its specificities and those of the locale when style is set to currency.

Examples

Format as plain number

monster.util.formatNumber({ number: 5 });                   // -> "5"
monster.util.formatNumber({ style: 'decimal', number: 5 }); // -> "5"
monster.util.formatNumber({ number: -5 });                  // -> "-5"
monster.util.formatNumber({ number: 5000 });                // -> "5,000"
monster.util.formatNumber({ number: '5.5' });               // -> "5.5"
monster.util.formatNumber({ number: 5.4321 });              // -> "5.432"
monster.util.formatNumber({ number: 5, digits: 3 });        // -> "5.000"
monster.util.formatNumber({ number: 5.55, digits: 1 });     // -> "5.6"

Format as price

monster.util.formatNumber({ style: 'currency', number: 5 });              // -> "$5.00"
monster.util.formatNumber({ style: 'currency', number: -5 });             // -> "-$5.00"
monster.util.formatNumber({ style: 'currency', number: '5.5' });          // -> "$5.50"
monster.util.formatNumber({ style: 'currency', number: 5.54321 });        // -> "$5.54"
monster.util.formatNumber({ style: 'currency', number: 5, digits: 3 });   // -> "$5.000"
monster.util.formatNumber({ style: 'currency', number: 5, digits: 1 });   // -> "$5.0"
monster.util.formatNumber({ style: 'currency', number: 5.5, digits:0 });  // -> "$6"

Format as percentage

monster.util.formatNumber({ style: 'percent', number: .5 });                // -> "50%"
monster.util.formatNumber({ style: 'percent', number: '.5' });              // -> "50%"
monster.util.formatNumber({ style: 'percent', number: 0.5 });               // -> "50%"
monster.util.formatNumber({ style: 'percent', number: -5, digits: 2 });     // -> "-50.00%"
monster.util.formatNumber({ style: 'percent', number: .555 });              // -> "56%"
monster.util.formatNumber({ style: 'percent', number: .12345, digits: 2 }); // -> "12.35%"
monster.util.formatNumber({ style: 'percent', number: .5, digits: 3 });     // -> "50.000%"
