<p class="MsoNormal">Hi team,<o:p></o:p></p>
<p class="MsoNormal">Reading the spec for JEP 455, I was puzzled with the following part:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><i><span style="mso-ligatures:none">The following conversions are unconditionally exact:<o:p></o:p></span></i></p>
<ul type="disc">

<i><span style="mso-ligatures:none">a widening primitive conversion which is: <o:p>

<li class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0 level2 lfo1">
<i><span style="mso-ligatures:none">from any integral type to any integral type and neither of them is

<i>
<o:p></o:p></i></li></ul>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">At first (at the first 5 times, I confess) I read it as an unconditionally exact conversion is, among others, a widening primitive conversion, e.g. a conversion from any integral
type to any integral type, but not char.<o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">I understand now that what was likely meant is that an unconditionally exact conversion includes, among others, a widening primitive conversion of integral types (but not char),
and that the reader has to refer to the definition of widening primitive conversion to understand the conversion of which type will be unconditionally exact and which ones are not.<o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">The difference here is that at first I thought the author re-defined a widening primitive conversion as a conversion from
<i>any integral type to any integral type</i>. <span style="mso-ligatures:none">a widening primitive conversion which is</span> is the wording that caused my confusion.<o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">Id like to confirm that my understanding is correct. Also, may it be a source of potential confusion for future readers of the spec?<o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">Thank you,<o:p></o:p></p>
