Apparently they like Kevin better than they like you :) Corey From: "Bruley, Peter T" <Peter.T.Bruley@xxxxxxxxxxxxxx> To: "foxboro@xxxxxxxxxxxxx" <foxboro@xxxxxxxxxxxxx> Date: 03/03/2011 04:35 PM Subject: [foxboro] HLBL Language and missing math functions PER Rejected Sent by: foxboro-bounce@xxxxxxxxxxxxx I wrote a Product Enhancement Request to make HLBL more functional: Problem Description: The HLBL language associated with IND sequence blocks is too limited in the math functions. For example how do I raise a number to the power of 3.456 (x^3.456) within the IND block? In C Programming language there is a MATH.h header file that includes Trigonometric, Exponential, Logarithmic, Power Functions along with other misc functions. In C there are also tools in the stdlib.h that can convert ASCii strings to floats/integers (atof, atoi, atol, etc) Maybe some more time functions would be nice to. Suggested Solution: Add a larger math function library to the HLBL compiler to incorporate more math functions. Add other libraries to HLBL that can do string/ASCii to float/integer conversions and vis-versa. Expected Benefit: Will be able to build complex curves such as steam tables, etc. -------------------------------------- Here is the answer I received: Dear Submitter, Thank you for your submission to enhance this product. However, after careful consideration, at this time there are no plans to include the requested functionality in the product roadmap. ----------------------------------- Perhaps if others on this list that believe this is a need enhancement could write similar PER's then perhaps Foxboro would reconsider and this functionality may be added in a future release. What do other users do to build equations that can't be done in the CALC or IND block because of limited math functions? or more precisely in my case a steam table lookup?
