The char type has from_digit() and from_u32() for getting a char from a digit or from a u32, but where are the converse functions for the integer types (all of them)?
i.e. I expected to see some uN::from_{char|digit}() and iN::from_{char|digit}() functions (where N is 8, 16, 32, 64 or size) for symmetry but apparently they do not exist.

the CHAR function takes just one argument, number, which must be an integer between 0-255. The result from CHAR is a text value. The CHAR function was designed to operate in an ASCII/ANSI world, and only understands numbers 0-255. For extended character support on modern Unicode systems, see the UNICHAR function.
It was introduced in Excel 2000 version and is available in all versions after that. 4. The CHAR function is the inverse of the CODE function. 5. Excel functions CHAR and UNICHAR will return the character for a given code whereas Excel functions CODE and UNICODE would do the opposite – give the code for a given character.
Formula =CHAR(number) The CHAR function uses the following argument: Number (required argument) – This is a number between 1 and 255 specifying which character we want. The character is from the character set used by our computer.
Below is the C++ program to convert char to int using sscanf (): 4. Using stoi The stoi () function in C++ converts a string to an integer value. Below is the C++ program to convert char to int using stoi (): 5. Using atoi If the execution is successful, the atoi () method returns the converted integer value.
The inverses are:
to_digit for from_digit: c.to_digit(12)
as u32 cast for from_u32: c as u32
The latter is the one you want if you want the Unicode codepoint of the char.
