Yes.
arrayFloat = randomu(s, 10)
arrayStrings = strtrim(findgen(10),2)
fileName = 'testFileOutput.txt'
get_lun, fileUnit
openw, fileUnit, fileName
printf, fileUnit, transpose(arrayStrings+', '+string(arrayFloat,FORMAT='(f0.3)'))
close, fileUnit
free_lun, fileUnit

Play a bit around with string() and the format keyword. A way or another, you will get what you want (constant width for the columns or number of decimals, separator, ...).

Cheers,
Helder
