Comma Separated Values in CAS

[Joe Horn]

Just in case the OP meant, "Can CAS display large numbers with thousands separators?" then I'm pretty sure that the answer is NO. No matter which Number Format or Digit Grouping you select in Home Settings, CAS never inserts any thousands separators. You can, however, use the STRING function in a CAS program to insert thousands separators into an output:

STRING(123456789,2,2,"1,000,000") --> "123,456,789"

See the Help screen for STRING for further information about its many formatting options.
