<b>Document:</b> WG14 N33??<br>
<b>Title:</b> N33??: SIGFPE and I/O<br>
<b>Reference Documents:</b>CFP 3095</p>
<p><b>Summary</b></p>
<p>7.12.1#1 says that SIGFPE is not allowed to be raised for any
<math.h> function. However, SIGFPE could be raised for an
I/O function or a numeric conversion function. For example,
<b>scanf</b> of 1e999999 is an overflow. So need a broader
statement.</p>
<p><b>Proposal</b></p>
<p>Add to "7.1.4 Use of library functions" another bullet:</p>
<blockquote>
Unless specified otherwise (e.g., <b>raise</b> function),
SIGFPE shall not be raised by any library function.
</blockquote>
