James,
Floating point values (real numbers) are indeed stored as four byte
(single precision) reals.
I once approached Perry Kaufman with the question posed below. His
response was that there are virtually no calculations we perform on price
data that require greater precision.
In the occasion that greater precision is required it is possible to
perform them in an external DLL using double precision values but, indeed,
the return value must once again be a single precision number.
