largest number we can use to assure exact precision in Javascript?
<p>I have not been able to find a straight answer on this. I've check the spec but don't see anything that defines the precision.</p>

<pre><code>Number.MAX_VALUE
    1.7976931348623157e+308
a = 9007199254740992
a == a-1
    false
a+1
    9007199254740992
a+2
    9007199254740994
a*a
    8.112963841460668e+31   
a*a == ((a*a)-1)
    true
a*a == ((a*a)*a)
    false
</code></pre>
