Use the Matlab builtin function: mean. This function converts the values to floats for us! Note : before a programmer relys on a Matlab function to accurately do the needed work, the programmer should test it! The uint8 Data Type uints are a type of integer. The u-int-8 stands for: U: Means: Unsigned Which means: All values are positive no negative "sign" allowed. What if we take an integer and divide it by a floating point number? Note: Matlab usually turns everything into doubles, so we don't have to worry about these situations.
It documents your intent - you will be storing small numbers, rather than a character. Improve this answer. Mark Ransom Mark Ransom k 40 40 gold badges silver badges bronze badges.
Explicitly using unsigned char or signed char documents the intent too, since unadorned char is what shows you're working with characters. I thought an unadorned unsigned was unsigned int by definition? Indeed, char seems to imply a character, whereas in the context of a UTF8 string, it may be just one byte of a multibyte character. Of course all C programmers know this, but it may push beginners to ask the right questions. I have to say, unsigned char isn't really used to store characters in the first place, so the "intent" issue is moot.

Pavel Minaev Pavel Minaev Skizz - No, the standard requires unsigned char to be able to hold values between 0 and If you can do that in 4 bits, my hat is off to you. It probably won't change existing behavior of cout backward compatibility! I found the detailed description of proposal. When it says underlying type, it means that is what the memory representation is, not what the type is.
Notice how it states that it is a distinct type? This means that the compiler will treat it as its own type. You can overload on the type and you can use it as a parameter for a template without it being confused for anything else.
Another way to put it is that underlying type is not the same as a typedef. So the code:. So it explicitly disables the use of this type. However, if you try to use unsigned char then it still works. But the reason why this wouldn't fix anything with iostream is still the simple fact that iostream hasn't been changed in regards to unsigned char.
The iostream library still defines unsigned char as a character type. The GNU C compiler extends the language to contain long long integers as well.
The C integer types were intended to allow code to be portable among machines with different inherent data sizes word sizes , so each type may have different ranges on different machines.
The problem with this is that a program often needs to be written for a particular range of integers, and sometimes must be written for a particular size of storage, regardless of what machine the program runs on.
