<p>
Returns a string representing the exact value of this Decimal in a compact base-88 based
format.
</p>
<p>
A Decimal instance with the same value as this Decimal can be created by passing the return
value to the <code><a href='#fromJSON'>fromJSON</a></code> method of a Decimal constructor.
</p>
<p>
The number of characters of the return value will always be equal to or less than the number
of characters returned by <a href='#toString'><code>toString</code></a> - usually just over
half as many.
</p>
<p>
The 7 printable ASCII characters, <code>(space) \ " & ' &lt; &gt;</code>, are not used in
the return value, so it should be safe for inclusion in HTML, JSON and XML.
</p>
<pre>
x = new Decimal('177.7e+457')
x.toJSON() // '25jkh'
y = new Decimal(235.4325)
y.toJSON() // '/3E1Z'
z = new Decimal('0.0098074')
z.toJSON() // '*cWG'
// Serialize an array of three Decimals

<p>If the <code>toJSON</code> method was not present, deserialization would be difficult as the
array would be serialized as:</p>
