float with 24-bit resolution

[mailbox@adrianhoe.nospam.com.my]

Hi,

I looked through the LRM and searched CLA but I could not find any
solution. Perhaps I've overlook somewhere.

I need a float with 24-bit resolution. My data needs to be encoded into
24 bits at a scaling of 720 degrees / 2^24 bits with the most
significant bit being the sign bit. This results in a value that ranges
from +359.9999571 degrees (0x7FFFFF) to -360.0000000 degrees (0x800000)
at increments of approximately 4.291534424e-5 degrees per bit.

The float and short_float have both 32-bit. I am using GCC3.3 that comes
with SuSE Linux 8.2 on Intel x86.

Is there a short_short_float for GCC 3.3?

How do I declare a float with 24-bit storage size?

Thanks in advance for your help.
