Proposal for new floating point and integer data types

[Brandon Andrews]

> float16/80

> decimal32/64/128


Those are reasonable additions also. Wasn't sure with decimal was going to assume 128 bit for financial type applications. Having it vary with 32, 64, and 128 bit thought is much closer to the other suggestions. (I updated my original post on esdiscuss to include them.)

I saw your esdiscuss post on Float16Array also.
