Don’t buy oil at 1 cent per barrel - that gift horse IS too good
Is the opinion that Julias type system would have saved the day here - even if a type was chosen which was not appropriate?
Looks like the price was able to go negative. but the display value not able, and also the margin calculation was wrong.
More serious question - the article clais a default display value of 1 cent. Does anyone really put in default values like this, rather than erroring or displaying ERROR, NaN, or something like that?
