Rounding

[emma78]

Hi,
may be you can help me :-)


Is it possible to round a number to the nearest 0.5 er values?

For example

3.26 should be 3.5
7.17 should be 7
7.6 should be 8


Is that possible?
Thank you!

compute z = rnd(2*z)/2.

or, trickier,

compute z = rnd(z, .5).

Do not do this.  Always keep it possible to go back and redraft your syntax
as the other responses to your post did.

put the result in a new variable.

compute newvar = rnd(2*z)/2.

Look at the rnd function in the syntax reference. I think you will find it inadequate for some of your examples and inadequate for others. I think you might be able to write a bit of syntax but I'm not sure. What I have in mind would exploit the difference between rnd(2*x) and 2*rnd(x).

3.26 should be 3.5 <<won't work.
7.17 should be 7  << will work.
7.6 should be 8  << will work.

BUT 8 is NOT closest to 7.6. 7.5 is the required result.
