<div>
<pre>It appears that an expression using any of the SNAN (signaling NaN) macros used
as the initializer of a floating-point variable is left as a SNAN. For
example:
static double d = SNAN + 3.; /* should be a quiet NAN */
The intent is only SNAN, +SNAN, -SNAN should be signaling NaNs, while any other
expression using a signaling NaN should be a quiet NaN.</pre>
