Round up to next half number

[rmb4253]

I am trying to round up a number to what I recall from school days to be
"correct to the nearest half". In other words, if the cell value is between
3.01 and 3.49 I want to round it to 3.5. If the cell value is 3.5 to 3.99 I
want it rounded to 4.0

I have managed to round up and down to the nearest whole number but can't
figure out how to get it to the nearest half! Can anyone help, please?

How's this =ROUNDUP(A1*2,0)/2
best wishes

You don't really want 3.5 to become 4 do you?

perhaps, if you only have positive numbers

=CEILING(A1,0.5

Bernard, Thanks very much - that is marvellous!

Happy to help

daddylonglegs,

Yes I did want 3.5 to become 4 - but thanks for the formula anyway - I've
never used "Ceiling" before! I'll have to read up on it!

For positive numbers

=ROUNDUP(A1*2,0)/2

does the same as

=CEILING(A1,0.5)

neither of them will return 4 when A1 is equal to 3.5, what result d
you want when A1 is 3

Daddylonglegs,

Thanks for that! Actually you were right when you said I wouldn't want 3.5
rounded up so what I need is if the result is 3, then I want it to stay as 3.
Result of 3.01 to 3.5 to be 3.5 and 3.51 to 4 to be 4.

Your suggestion and that of Bernard's both do that so thanks again!
