/**
 * Represents a relative value (percent).
 *
 * The Percent object, can be instantiated using two ways:
 *
 * * Via `new Percent(X)`.
 * * Via `am4core.percent(X)`.
 *
 * `Percent` type objects can be used in a number of dual-measuring or
 * positioning properties, like `width`. E.g.:
 *
 * ```TypeScript
 * chart.paddingRight = new Percent(10);
 * // or
 * chart.paddingRight = am4core.percent(10);
 * ```
 * ```JavaScript
 * chart.paddingRight = new Percent(10);
 * // or
 * chart.paddingRight = am4core.percent(10);
 * ```
 * ```JSON
 * {
 *   // ...
 *   "paddingRight": "10%"
 * }
 * ```

     * Relative value.
     *
     * E.g. 100% is 1, 50% is 0.5, etc.
     *
     * This is useful to apply transformations to other values. E.g.:
     *
     * ```TypeScript
     * let value = 256;
     * let percent = new am4core.Percent(50);
     * console.log(value * percent.value); // outputs 128
     * ```
     * ```JavaScript
     * var value = 256;
     * var percent = new am4core.Percent(50);
     * console.log(value * percent.value); // outputs 128
     * ```
     *
     * Alternatively, you can use `am4core.percent()` helper function:
     *
     * ```TypeScript
     * let value = 256;
     * let percent = am4core.percent(50);
     * console.log(value * percent.value); // outputs 128
     * ```
     * ```JavaScript
     * var value = 256;
     * var percent = am4core.percent(50);
     * console.log(value * percent.value); // outputs 128
     * ```
