Operation of WPP[edit] WPP is run prior to compilation (in other words, before even the C preprocessor), and generates a trace message header for each file that it processes (by default this header is filename.tmh, where filename is the name of the processed source file). WPP's understanding of C/C++ syntax is very limited.
Divide the new value by the old value and multiply by 100 to find the absolute relationship between the two values. A process that is similar (but not identical) to the process used to find percent change is that used to find the absolute percentage relationship between the old and new values.
1 Step 1: Write down the percent divided by 100. 2  Step 2: If the percent is not a whole number, then multiply both top and bottom by 10 for every number after the decimal point.( 3 For example, if there is one number after the decimal, then use 10, if there are two then use 100, etc.). Step 1: Write down the percent divided by 100. 2  Step 2: If the percent is not a whole number, then multiply both top and bottom by 10 for every number after the decimal point.
