My ladder program's comparison commands don't work properly.

The comparison commands of the digital indicating controllers (UT55A/UT52A/UT35A/UT32A) and program controllers (UP55A/UP35A) compare integers (rounded to the nearest decimal). If making comparisons that include decimals, first multiply the necessary constants (C10 (constant 10) and C100 (constant 100), etc.) before executing the commands. The UT75A Digital Indicating Controller also allows comparisons of floating point numbers.
