Hi

I have the following problem....
I have an array of float numbers consisting of many decimal points and
I want to convert it to string ... I used the string command but how
can I isolate and keep only the first 3 digits from each element of the
array? I played with the format keyword but... a mess...
can anyone help?

Well... the original poster did not say that he/she wanted only the
first 3 most significant digits, just the first 3 digits... so I
thought strmid() was the simplest answer:

first3 = strmid(string(var),0,3)

I'm not sure why one would use STRMID in this case -- you can use it to
cut out substrings, but why not format correctly in the first place
rather than specifying too many digits first and then cutting off what
you don't want?
