PTC Mathcad Express _ Prime 10.0.0.0 _ Percentage Calculation showing wrong reults

Hello All,

 

I am attempting to find the percentage deviation of the calculated output.

However, in Mathcad Prime, the calculation using matrix indices is producing incorrect results.

What could be causing this issue?

 

In the attached screenshot, the output calculation in green font is correct and was done manually, while the output calculation in red font is incorrect and was done using the matrix indices formula.

I have attached the .mcdx file with my calculations for your reference.

I would greatly appreciate a quick resolution to this problem.

 

Thanks in Advance.

On contrary -  Primes "red font" calculation is the correct one!

Your manual calculation uses just values rounded to three decimals - hence the difference in the results.

If you use the exact values, the manual calculation agrees with Prime's results:

By default Prime shows three decimals in results. This can be altered - either for a single result or for all results in the sheet (which have not been formatted manually) depending on where the cursor is placed while you change the setting.
