Fixed point is a "lossless" way to represent decimal fractions. Standard
floating-point uses binary internally, and so "0.01" can't actually be
 represented properly (just as 1/3 can't be represented completely in
decimal -- 0.33333...). Fixed point is generally implemented by using
integers and keeping track of where a decimal point ought to be. (Addition
is straightforward, multiplication/division gets an extra step.)

It's also not in the C++ standard library, as far as I know.
