Variable floatToPercentConst

Type Declaration

• • (num: number, fixSize?: number): string

  • Format a numeric ratio as a percentage string.

    Multiply by 100. Falsy precision uses Math.floor, including for negative ratios; truthy precision uses native toFixed and preserves trailing zeros. Floating-point arithmetic and native precision conversion remain unchanged.

    Usage:

    import { formatPercentage } from "mazey";
    
    const ret1 = formatPercentage(0.2);
    const ret2 = formatPercentage(0.2, 2);
    console.log(ret1);
    console.log(ret2);
    Copy

    Output:

    20%
    20.00%
    Copy

    Parameters

    • num: number

      Floating-point ratio to convert.

    • fixSize: number = 0

      Number of decimal places, defaulting to 0.

    Returns string

    The percentage string.

    Throws

    If native toFixed rejects a truthy precision value.
