    Properties

    binary?: boolean

    Format the number using the Binary Prefix instead of the SI Prefix. This can be useful for presenting memory amounts. However, this should not be used for presenting file sizes.

    import formatBytes from '@oliversalzburg/js-utils/format/bytes.js';

    formatBytes(1000, {binary: true});
    //=> '1000 bit'

    formatBytes(1024, {binary: true});
    //=> '1 kiB'
    bits?: boolean

    Format the number as bits instead of bytes. This can be useful when, for example, referring to bit rate.

    import formatBytes from '@oliversalzburg/js-utils/format/bytes.js';

    formatBytes(1337, {bits: true});
    //=> '1.34 kbit'
    locale?: string | boolean | readonly string[]
    • If false: Output won't be localized.
    • If true: Localize the output using the system/browser locale.
    • If string: Expects a BCP 47 language tag (For example: en, de, …)
    • If string[]: Expects a list of BCP 47 language tags (For example: en, de, …)
    maximumFractionDigits?: number

    The maximum number of fraction digits to display.

    If neither minimumFractionDigits or maximumFractionDigits are set, the default behavior is to round to 3 significant digits.

    import formatBytes from '@oliversalzburg/js-utils/format/bytes.js';

    // Show the number with at most 1 fractional digit
    formatBytes(1920, {maximumFractionDigits: 1});
    //=> '1.9 kB'

    formatBytes(1920);
    //=> '1.92 kB'
    minimumFractionDigits?: number

    The minimum number of fraction digits to display.

    If neither minimumFractionDigits or maximumFractionDigits are set, the default behavior is to round to 3 significant digits.

    import formatBytes from '@oliversalzburg/js-utils/format/bytes.js';

    // Show the number with at least 3 fractional digits
    formatBytes(1900, {minimumFractionDigits: 3});
    //=> '1.900 kB'

    formatBytes(1900);
    //=> '1.9 kB'
    signed?: boolean

    Include plus sign for positive numbers. If the difference is exactly zero a space character will be prepended instead for better alignment.

    space?: boolean

    Put a space between the number and unit.

    import formatBytes from '@oliversalzburg/js-utils/format/bytes.js';

    formatBytes(1920, {space: false});
    //=> '1.9kB'

    formatBytes(1920);
    //=> '1.92 kB'
