Line 1,679: ===version 3=== ~~This~~When factoring   20,000 integers, this REXX version is over 12% faster than the REXX version 2 ~~  (more so when specifying larger numbers)~~. <br>When factoring 200,000 integers, this REXX version is over 25% faster. It accomplishes a faster speed by incorporating the calculation of an   ''integer square root''   of an integer   (without using any floating point arithmetic).
