The processor parameter values are displayed with two decimal places by default. However, when these values become very large and exceed about 7 text symbols, the text is too long to fit the label and it'll simply not show up. This commit fixes that by disabling the decimal place for such large values, which allows us to show values up to 9,999,999, be it only at integer precision.
