constexpr-to-string
Features:
- Convert any integral type to a string at compile-time
- String can be in binary, hexadecimal, or any base in-between
- No external dependencies, only includes
type_traits
for type-checking - Works best in C++20 GCC or C++17/20 Clang
How to use:
This single header file provides a to_string
utility, which may be used as below:
const char *number = to_string<2147483648999954564, 16>; // produces "1DCD65003B9A1884"
puts(number);
puts(to_string<-42>); // produces "-42"
puts(to_string<30, 2>); // produces "11110"
With to_string
, all that will be found in program disassembly are the resulting string literals, as if you wrote the strings yourself.
Known issues:
- With C++17 GCC,
to_string
must be used to initialize variables; otherwise, the integer-string conversion is done at run-time.
