I'd like to make sure I'm interpreting the tea leaves the<br>proper way for 7.12.9.10p2. The confusion comes from this bit:<br><br>Otherwise, if width is zero or x does not round to an integer within<br>the range, the functions return a NaN (of the type of the x argument,<br>if available), else the value of x, and a domain error occurs.<br><br>Are the parentheses slightly wrong there? I think the only way I can<br>make sense of this is as-if it were written:<br><br>Otherwise, if width is zero or x does not round to an integer within the range<br> * the functions return a NaN (of the type of the x argument), if available,<br> * else the value of x,<br>and a domain error occurs.<br><br>Is that a correct interpretation? If so, should the parens move to not<br>include "if available"?<br><br>Thanks!<br><br>~Aaron</span></div></div></div></div></div></div></blockquote></div><br></div></div></body></html>
