Line 679:
Note that the '''iSqrt''' subroutine doesn't use floating point.
The REXX statement (line 22) ''if pos(.,_)\==0'' isn't normally used for a general-purpose check if a number is an integer (or not),
<br>this version was used because it's faster then the usual statement: ''if \datatype(_,'Whole')'' and because the number is well-formed.
This REXX program doesn't need to explicitly sort the triangles.
