IN or RCPY do not lie in the range [0, 100] or INPD lies outside the range [-100, 100].
To calculate the function block uses a value that is limited by the next closest correct value, i.e. 0, 100 or –100, depending on the value.
For the list of other possible floating point error codes, see Common Floating Point Errors.
