Wrong token amount on Make a decision

[bingen]

If I put 50it results in 50.50, 10 in 10.10... See screenshots:

I didn't completely take away this buffer but I've lessened it. This is kind of convoluted but the smart contract only allows you to specify how much outcome tokens ( <-- these prices fluctuate) you'd like to buy, as opposed to how much TKN you'd like to spend on buying outcomes. so we have to do these calculations on the client-side and we need a small buffer above the the buy price in order to not error out. instead of 1% I've made it 0.1%. Taking this away completely will take some time on our part, so lessening this for now.
