If you could post the code that duplicates this output, it would be
easier to tell.
However if you take a text string and add an integer to it, it will be
converted to an integer type.
The INF you have showing means 'infinity', but I am not sure how you are
getting it.
Try gettype() in your output to see what type it is getting converted to.
