$(D_PSYMBOL isNormal).
Determines whether x is a denormilized number or not.
Denormalized number is a number between 0 and 1 that cannot be represented as
<pre> m*2<sup>e</sup> </pre>
where m is the mantissa and e is an exponent that fits into the exponent field of the type F.
0 is neither normalized nor denormalized.
