 # Pearson verify
 This program is meant to be used to verify the ouput of the pearson section of [dv1674_a2](https://github.com/sm13294/dv1674_a2).\
 \
-This program compares 64 bit floating point numbers stored in a separate line each from \<file1\> and \<file2\>. If all the pairs of numbers are the same up to the 15th decimal place, 0 will be returned. If not, this program will check if all numbers are the same up to the 11th decimal place, and if so 1 will be returned. If [stop] is 1, this program will stop as soon as this happens. If any numbers are not the same up to the 11th decimal place, 2 will be returned. If [stop] is 2, this program will stop as soon as this happens. If there is an error while executing this program, -1 will be returned.

If there is an error while executing this program, -1 will be returned, unless the error lies within the files' structures, in which case 2 will be returned, as it means there was a significant difference in the outputs. Compile with -DDEBUG (make debug) or define DEBUG in the program to print debug information.
