Why no unsigned float

You can get around not having an unsigned floating point type though by creating a unsigned float class that encapsulates a float or double and throws warnings if you try to pass in a negative number.

This is less efficient, but probably if you aren't using them intensely you won't care about that slight performance loss. I definitely see the usefulness of having an unsigned float. The reason there is no unsigned float is that you quickly run into all sorts of problems if there are no negative values. Consider this:. But, alas they are not there. All floating points are signed. As the floats already take up at least 32 bits, the gain of having a software implementation that would regain that 1 bit is insignificant compared to the usefullness of such an implementation.

You can determine the native data model for your system using isainfo -b. The names of the integer types and their sizes in each of the two data models are shown in the following table.

Integers are always represented in twos-complement form in the native byte-encoding order of your system.
