IEEE-754-2008 standard questions

May be my query is more appropriate for the comp.arch.arithmetic
forum, but lately it has
become filled up by spam and trash. I have a
few questions regarding the IEEE-754-2008
standard.
As per this standard, the general format for a
32 bit number converted to his format is
1 bit for sign, 8 bits for exponent and 23 bits
for mantissa/significand. The mantissa is
always of the form 1.<fraction part>. So for
example, 12.375 converted to this format is
1.5468.., with exponent of 3. The standard
32 representation does not contain the "1.",
-- the "hidden bit".
So, given all of this, how would one convert
a number from the IEEE-754-2008 format
to the standard human understandable form.
For example, 2*12.375 = 24.75, but in the
IEEE-754-2008 32-bit format it is 1.<some
fraction>
Any hints/suggestions would be greatly
appreciated. Thanks in advance for your help.
