[comp.sys.amiga.tech] Floating point format

I need to know the binary storage format of amiga floating
point numbers (single precision 32bits) for a program I'm
trying to simulate for class.   According to Jake Commander's
AMIGA Assembly Language Programming, the layout is :

   8bits for the exponent stored in two's complement
   24 bits for the mantissa w/ MSB as the sign bit.
    
Is this correct?   Is there a format like that of the PDP-11
or AT&T 3B2's where the MSB of a 32 bit word is the sign
of the mantissa, followed by 8 bits bias exponent, and 23 bits
for a normalized mantissa with the MSB (always a 1) not stored.
???
