rounding to nearest HALF digit

This is just a neat little idea if perhaps anyone wants to round numbers, oh,
just a little differently.

Let h mean half or a sort-of 5 in the digit where an h is.  Let z mean zero.

Here are some example numbers.

6250 < 6h00 < 6750  (The h here means 500 plus or minus 250, exclusive)

6750 <= 7z00 <= 7250 (The z here means plus or minus 250, inclusive)

1.5025 < 1.50h < 1.5075 (The h here means 0.005 but with plus or minus 0.0025)

Re: rounding to nearest HALF digit

you may compare its competence with common rounding and the half's exponents system 1/2 1/4 1/8 ...
