<div dir="ltr">Your pointing to two mutually exclusive protocols proves the point. If I want to write a generic function for a numerical type which can be added, I can't just require that the type conforms to IntegerArithmeticType because that excludes all the floating point types. Protocols for various numerical functions, e.g. NumericalArithmeticType, would be handy,</div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Apr 11, 2016 at 4:55 PM, Joanna Carter via swift-evolution <span dir="ltr"><<a href="mailto:swift-evolution@swift.org" target="_blank">swift-evolution@swift.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><span class=""><br>
