An IEEE-754 format floating-point number has one sign bit, eight
exponent bits, and 23 mantissa bits.
Addendum: 23 mantissa + 1 sign essentially gives 24 bits of precision.
I'm used to thinking of the 23 mantissa bits separately from the sign
bit, but I don't want to imply that a floating point number has only 23
bits of precision; really it has 24.
Thanks to Joe Bryan for the alert ..
