There is a use case for me that I am given a string, and before
even trying to convert it to integer, I want to check whether
it is valid. One of the checks necessary for this is the length
of string.
So, if I have received "156" and it should be converted to
ubyte, I would check whether it is at most 3 bytes length.
While doing that someone would define that maximum length in
the code, while length information is constant and never
changes.
For this reason, however data types have properties like max,
min, and init, I would ask for addition of new properties for
integral (even for floating points as well) types as (Example
values for ubyte):
max_hex_length = 2
max_dec_length = 3
max_bin_length = 8
enum max_hex_length = T.sizeof * 2;
enum max_bin_length = T.sizeof * 8;
enum max_dec_length = cast(T)log10(T.sizeof) + 1;
