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.
Change Net / % Net Change is the difference in the current last sale price and the previous days' closing price. Percent Change is the amount in percentage terms that the last sale price for the stock has changed from the previous trading days' closing price.
