# compare_values

`psi4.driver.``compare_values`(expected, computed, digits, label, exitonfail=True)

  Function to compare two values. Prints `util.success()` when value computed matches value expected to number of digits (or to digits itself when digits < 1 e.g. digits=0.04). Performs a system exit on failure unless exitonfail False, in which case returns error message. Used in input files in the test suite.
