rounding to the next 0.5

[badbadtzmaru]

I need to round a figure say 3.2 up to the nearest 0.5 so it will become 3.5 but i do not know how to do so as it always round to the nearest integer, from 3.2 to 4.

Need to know how to do round to 0.5 

Pls help.

This will roundup anything above 3 but below 3.5 to 3.5.  From 3.5 to 4, it rounds up to 4.0.  However, due to representation errors, sometimes a .5 rounds up to the next integer, sometimes it doesn't.  For example, 10.5 will remain 10.5, but 9.5 will round up to 10.  At least that is how it does on my system.

Double.  Round up. Divide by 2.

And how to round to the nearest 0.5 multiple:

3.2 -> 3
3.6 -> 3.5
3.8 -> 4

For the record MGI Librairies have this function and much much more.
