Mutual fund prices precision

I know the share count matters, but the share count is wrong and I can't
get it working properly to match the statements.  Doesn't matter if I
let GC compute the price or compute the buy/sell total, it still seems
to be off slightly in the share totals.

For one account the shares as listed on the statement are 950.971 but GC
is computing 949.632 even though I started the account from scratch and
entered every transaction manually.  Most of the other funds differ in
shares by 0.01 but this one is a larger difference of a whole point.
This is also the only account where most of the prices have
autocorrected themselves so that's why I'm suspicious of the things
going on in the background.
