Subject: 6.3.4 Infix Operator "/"
Greetings! More of a note than a question: We say: > *Semantics:* Divides numbers. Due to the way conversion works, logical > values are converted to numbers. Dividing by zero returns an Error. > Applications *shall* support fractions, so 1 / 2 must produce 0.5, not 0. > First, we already define implicit conversion so the first sentence is repetition. Second, this isn't where conformance for applications would be defined. Even assuming that constraining applications is within scope, all that needs to be done here is to define the function. Third, the syntax says: Number Left / Number Right. If implicit conversion is in place, then why the Number Left / Number Right? Oh, is that to signal the outcome of conversion? BTW, I am not sure about "fraction support" = "1/2 must produce 0.5, not 0." I would think fraction support means it supports operations on fractions, not conversion to decimal values. Or is that a specialized usage in spreadsheet circles? Hope everyone is having a great day!
