Sometimes you need float packed in memory efficiently.

This might be useful in graphics, for example.

In general, I believe it is good to give people options. You never know what people will find useful.

But if you don't want support it and you feel it will make your language better, just don't support it.

But please, quit bitchin' about it.

Java does not support unsigned integer type and everybody is fine.

And Java devs don't write rants about how unsigned integers are useless, supporting them is annoying and everybody should just forget about them.
