Junio C Hamanoc14e6ad2014-10-31 20:25:53[diff] [blame]1560 file&#8217;s size). For example, <code>-M90%</code> means Git should consider a
Junio C Hamanoe85e36f2010-08-10 05:30:14[diff] [blame]1561 delete/add pair to be a rename if more than 90% of the file
Junio C Hamanoc14e6ad2014-10-31 20:25:53[diff] [blame]1562 hasn&#8217;t changed. Without a <code>%</code> sign, the number is to be read as
1563 a fraction, with a decimal point before it. I.e., <code>-M5</code> becomes
1564 0.5, and is thus the same as <code>-M50%</code>. Similarly, <code>-M05</code> is
1565 the same as <code>-M5%</code>. To limit detection to exact renames, use
1566 <code>-M100%</code>. The default similarity index is 50%.
