It's one thing if a language outputs one, two, or zero for this expression. Two and zero are mathematically wrong, but at least they're predictable.

It's another thing if a language sometimes outputs two and sometimes outputs one depending on the syntax of the request. This is reasonable where that syntax change is not an explicit cast to double precision or single precision, but dangerous if it uses a behind-the-scenes default of arbitrary precision in compiled literals and a default of FP32 in implicitly typed literal assignments.
