Better rounding on rate conversion?

[thejpster]

When doing rate conversion, fugit multiplies by RD_TIMES_LN and divides by LD_TIMES_RN in

fugit/src/rate.rs

Line 220 in 0ad21f7

let raw = lh / Helpers::<I_NOM, I_DENOM, NOM, DENOM>::LD_TIMES_RN;

.

Should it add half of LD_TIMES_RN to do half-up rounding?

I expect Rate<u32, 1, 1>(12_000_000) to convert to Rate<u32, 1000, 65536>(0x0020c49c) but instead I get Rate<u32, 1000, 65536>(0x0020c49b).

Converting 0x0020c49b back I get 32767.990 (error 0.01) whereas 0x0020c49c gives 32768.005 (error 0.005).

Am I holding it wrong?
