Function std.conv.toChars
Convert integer to a range of characters. Intended to be lightweight and fast.
auto auto toChars(ubyte radix = 10, Char, LetterCase letterCase = LetterCase .lower, T)
(
T value
) pure nothrow @nogc @safe
if ((radix == 2 || radix == 8 || radix == 10 || radix == 16) && (is(Unqual!T == uint) || is(Unqual!T == ulong) || radix == 10 && (is(Unqual!T == int) || is(Unqual!T == long))));
Parameters
Name | Description |
---|---|
radix | 2, 8, 10, 16 |
Char | character type for output |
letterCase | lower for deadbeef, upper for DEADBEEF |
value | integer to convert. Can be uint or ulong. If radix is 10, can also be int or long. |
Returns
Random access range with slicing and everything
Example
import std .algorithm .comparison : equal;
assert(toChars(1) .equal("1"));
assert(toChars(1_000_000) .equal("1000000"));
assert(toChars!(2)(2U) .equal("10"));
assert(toChars!(16)(255U) .equal("ff"));
assert(toChars!(16, char, LetterCase .upper)(255U) .equal("FF"));
