formatPercent()function

formatPercent(numerator: number, denumerator?: number, options?: PercentFormatOptions): string

Param	Type
`numerator`	`number`	Number representing the amount of progress (e.g. `50`). required
`denumerator`	`number`	The number representing the whole amount (defaults to 100).
`options`	`PercentFormatOptions`	Formatting options passed through to `Intl.NumberFormat`.

Return
`string`	Locale-formatted percentage string.

Format a percentage (combines getPercent() and formatUnit() for convenience).

Defaults to showing no decimal places.
Defaults to rounding closer to zero (so that 99.99% is shown as 99%).
Javascript's built-in percent formatting works on the 0 zero to 1 range. This uses getPercent() which works on 0 to 100 for convenience.

Examples

formatPercent(50) // "50%"
