Sure. Multiply either number by 1AU and the difference is not insignificant

Me too. But the fault would lie with the spacecraft system programmer, not the language
(be it IDL or something else).

Actually, the fault would lie with the programmers' supervisor/manager for a) assigning an
inexperienced person to produce the code and/or b) for not establishing useful QC/QA
processes that should catch these sorts of naive coding errors.
