[cmplx.over], [cmath.syn] use of undefined phrase "effectively cast"

[jensmaurer]

What kind of cast are we talking about here? reinterpret_cast?

Likely we mean "apply floating-point promotions, floating-integral conversions, and floating-point conversions", but that should be spelled out somewhere, e.g. in the library definitions section.

Alternatively, just saying "converted" (with an optional cross-reference to [conv]) should be sufficient.

Subject: New LWG issue: undefined phrase "effectively cast"
To: Marshall Clow lwgchair@gmail.com

In [cmplx.over] and [cmath.syn], when talking about
"sufficient additional overloads", we use the phrase
"effectively cast", but that is not a defined term.

A hostile interpretation could read "reinterpret_cast"
here.

Likely we mean "apply floating-point promotions, floating-integral
conversions, and floating-point conversions", but that should be
spelled out somewhere, e.g. in the library definitions section.
