Bug in zero separation of big number calc float outputs

[defuse]

"I thought you might like to know of a small bug re the spacing of zeroes when multiplication involves numbers with decimal points. For example, 20150000 * 3.5 yields 7 052 500 0.0, whereas the spacing of 000 should obviously be 70 525 000.0"

I didn't even realize floating point worked, might be best to just disallow it. Or fix the bug. I'll probably never get around to doing either.
