you want your shares to be dividable? if no your precision should be "0" .. if you want it like USD dollar ... with up to 99 cents .. your precision should be "2"
in short: decimal places
nooooo it should be 100
oh damnit ... sorry
it 10 to the power of 0 and 10 to the power of 2 ;-)
thanks for correcting me ...
BTW. there is a testnet running (resets sometimes) it is in the github.com/BitShares repos and is called bitshares_toolkit ..
some devs can send you some funds and you can play around with the assets for free
