FORTH for the PC-G850(V)(S)

Brilliant!

I'm using a relatively simple but inefficient approach for converting strings to single-precision floating-point: use multiple-precision arithmetic and tables to find integers s,e such that s x 2^e = user input, where s element of [2^23,2^24) and is rounded up. Then use s,e to obtain the IEEE 754 single-precision encoding.

Its working for the few values I've tested (0.5 -> 0x3F000000, 2 -> 0x40000000 and 2.5 -> 0x40200000). Once I've added higher powers of 10 to the table and parsing exponents I'll try smaller and bigger values.

For floating-point to string I'll use the first algorithm in this paper.
