You don't need to use text field to validate that a number field contains an integer. To do it you should use "Boolean validator with math, date-time or text-string terms" wit the following boolean expression:

{nnnnn} = round({nnnnn})

If you want to remove the fractional part of a number field, you can use "Mathematical and date-time expression calculator" with the following formula:

floor({nnnnn})

replacing nnnnn with the corresponding field code.

You can validate whether a text field contains an integer using "Boolean validator with math, date-time or text-string terms" the following boolean expression:

matches(%{nnnnn}, "\\s*[-+]\\s*?\\d+\\s*")

replacing nnnnn with the corresponding field code.
