Subject: Linear Regression Test: Provide more decimal places in test results.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2ed1742f807f9a4bd7e9281bee0cc6e25801874e;p=pspp

Linear Regression Test: Provide more decimal places in test results.

This test previously had only 2 decimal places displayed, which
limited its ability to detect numerical errors.  This change increases
the decimal places to 3.

The results for this test were checked against a pattern provided
by Olaf Nöhring.
