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 Note that subtracting by 100% gives us 40 - 100 = -60%, the percent change we found above. 2  This process can give answers over 100% For instance, if $50 is our old price and $75 is our new price, 75/50 Ã100 = 150% 3  . This means that 75$ is 150% of 50$.ivide the new value by the old value and multiply by 100 to find the absolute relationship between the two values.
