Compiler does not have a problem with that and we've already established it
won't change anything since 'digits' are always lower then then 128-255 range
the cast protects.
Although it's not a compiler issue and the casts look ugly,
I want to ask those who'll use functions like them to use unsigned char
variables in the first place. I've ever spotted numerous mistakes
all over the code. That's why I hope they will leave there as my warnings.

p.s. (int)((char)-1) yields -1, rather than 255 of cource.
