Rounding decimal

Hi all,
I have to write a snippet that performs a rounding of decimal value, follow
this rules:

1.49m -1m
1.5 -2m
1.51 -2m

-1.49 --1m
-1.50 --2

I was trying this:

Math.Ceiling((-voceValue.Value ?? 0m) - 0.5M);

but not works correctly.

Has anyone idea?

Thanks a lot.

Math.Round has an overload that accepts a MidpointRounding value. You
can set that to "ToEven" or "AwayFromZero". I guess you need the second
value.

A small correction for negative values.
These are the rules:

-1.5 = - 1

- 1.6 = - 2

-1.4 = - 1
