The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

How can I calculate percentage value +ve/-ve growth between 2 values when one or both are negative?

Asked by deloptis in Crystal Reports Software, Business Objects, Math & Science

Tags: Crystal Decisions, Crystal Reports, 10

Hi,

I am trying to calculate the % increase / decrease between profit figures from previous to current year. Currently my formula is as follows:

If Sum ({@Current}) <> 0 and Sum ({@Previous}) <> 0 Then
((Sum ({@Current) - Sum ({@Previous}) / Sum ({@Previous})) * 100

It is fine if the current & previous years are both positive or if the previous year is positive and current is negative.

If however the previous year is negative then the values are correct but are incorrectly shown as +ve or -ve percentages (dependant upon current year figure)

I simply want to show a positive % if there has been an increase or a negative % if there has been a decrease, regardless of whether one or both figures are negative. So an example

Previous Year = -200
Current Year = 0

Increase = 100%

Does anyone know how to do this in Crystal?

Thanks in advance!!
