Are these two functions the same?

Feb 26, 2013
TCC 15.01.52 x64 Windows 7 [Version 6.1.7601]
TCC Build 52 Windows 7 Build 7601 Service Pack 1

Reading the help file it would appear that the built-in functions @ISDIGIT and @DIGITS are identical, which leads me to ask

  • Am I correct, are they identical?
  • If they are identical, is one of them deprecated or are they just synonyms (like RD and RMDIR)?

P.S. sorry about the typo in the title but I don't seem to be able to edit that...
