D004 float_not_finite
Float.round or a float-to-int conversion was given NaN or ±∞.
A runtime defect: the running program stops with it; no compile phase reports it, and try cannot catch it. sakura explain D004 prints this explanation offline.
Float.round or a float-to-int conversion was given NaN or ±∞. Check the value before
converting it; NaN and infinities come from dividing by zero or from overflowing arithmetic on
Float.
Runtime defects come from running programs, so compiler/tests/ui has no fixture for them; the explanation above names the repair.
