precision getting?

I need to find out the precision on a solaris machine using the unix terminal.
How do I find this out?

Specifics needed:
How are single precision numbers represented (8 or 16 bit)
How are double precision numbers represented (16 or 32 bit)
How are they stored. ( some computers store numbers with more bits than they print out)

Any help would be greatly appreciated.

Sun uses IEEE standard floating point numbers. Standard Precision is 32 bits and double precision is 64 bits. There is also long double which is 128 bits on a sparc but only 80 bits if solaris is running on an intel.
