An IEEE-754 format floating-point number has one sign bit, 8 exponent
bits, and 23 mantissa bits.
Addendum 2: note that the 24-bit range comes from the "understood 1".
Most 32-bit IEEE-754 numbers have an implied 1 bit to the left of the
binary point. In a way, this extra bit is contained or "spread across"
the exponent bits.
There are more details about this, but I won't bore you with them ..
lots of good references on the Net.
OK, I'm done :)
