toDigit Int? toDigit(Int radix)

Convert this number into a Unicode char 0-'9'. If radix is greater than 10, then use a lower case letter. Return null if this number cannot be represented as a single digit character for the specified radix.

toDuration Duration toDuration()

Convert nano-seconds ticks to a Duration. Convenience for Duration.make.

toHex Str toHex(Int? width)

Return hexdecimal string representation. If width is non-null, then leading zeros are prepended to ensure the specified number of nibble characters.

255.toHex(4)  =>  "00ff"

toLocale Str toLocale(Str? pattern, Locale locale)

Format this integer number for the current locale. If pattern is null, then the locale's default pattern is used. See Float.toLocale for pattern language. Fractional formatting is not supported for integers.

In addition Int.toLocale supports the "B" pattern which will format a number of bytes with the appropriate B, KB, MB, GB suffix based on the magnitude (1024B == 1KB).

Examples:

3.toLocale("00")             =>  03
3.toLocale("000")            =>  003
123456789.toLocale("#,###")  =>  123,456,789
123.toLocale("B")            =>  123B
1234.toLocale("B")           =>  1.2KB
100_000.toLocale("B")        =>  98KB
(3*1024*1024).toLocale("B")  =>  3MB

toRadix Str toRadix(Int radix, Int? width)

Return string representation in given radix. If width is non-null, then leading zeros are prepended to ensure the specified width.

Examples:

255.toRadix(8)    =>  "377"
255.toRadix(8, 5) =>  "00377"

toStr virtual Str toStr()

Return decimal string representation.
