<dd><p>Return non-zero iff the value of <var>op</var> fits in an <code>unsigned long int</code>,
<code>signed long int</code>, <code>unsigned int</code>, <code>signed int</code>, <code>unsigned
short int</code>, or <code>signed short int</code>, respectively. Otherwise, return zero.

<dt><a name="index-mpz_005feven_005fp"></a>Macro: <em>int</em> <strong>mpz_even_p</strong> <em>(const mpz_t <var>op</var>)</em></dt>
<dd><p>Determine whether <var>op</var> is odd or even, respectively. Return non-zero if
yes, zero if no. These macros evaluate their argument more than once.
</p></dd></dl>
<dl>
<dt><a name="index-mpz_005fsizeinbase"></a>Function: <em>size_t</em> <strong>mpz_sizeinbase</strong> <em>(const mpz_t <var>op</var>, int <var>base</var>)</em></dt>
<dd><a name="index-Size-in-digits"></a>
<a name="index-Digits-in-an-integer"></a>
<p>Return the size of <var>op</var> measured in number of digits in the given
<var>base</var>. <var>base</var> can vary from 2 to 62. The sign of <var>op</var> is
ignored, just the absolute value is used. The result will be either exact or
1 too big. If <var>base</var> is a power of 2, the result is always exact. If
<var>op</var> is zero the return value is always 1.
</p>
<p>This function can be used to determine the space required when converting
<var>op</var> to a string. The right amount of allocation is normally two more
than the value returned by <code>mpz_sizeinbase</code>, one extra for a minus sign
and one for the null-terminator.
</p>
<a name="index-Most-significant-bit"></a>
<p>It will be noted that <code>mpz_sizeinbase(<var>op</var>,2)</code> can be used to locate
the most significant 1 bit in <var>op</var>, counting from 1. (Unlike the bitwise
functions which start from 0, See <a href="Integer-Logic-and-Bit-Fiddling.html#Integer-Logic-and-Bit-Fiddling">Logical
and Bit Manipulation Functions</a>.)
