<h1><a name="description">DESCRIPTION</a></h1>
|
|
<p><code>BN_cmp()</code> compares the numbers <strong>a</strong> and <strong>b</strong>. <code>BN_ucmp()</code> compares their
|
|
absolute values.</p>
|
|
<p><code>BN_is_zero()</code>, <code>BN_is_one()</code> and <code>BN_is_word()</code> test if <strong>a</strong> equals 0, 1,
|
|
or <strong>w</strong> respectively. <code>BN_is_odd()</code> tests if a is odd.</p>
|
|
<p><code>BN_is_zero()</code>, <code>BN_is_one()</code>, <code>BN_is_word()</code> and <code>BN_is_odd()</code> are macros.</p>
|
|
<p>
|
|
</p>
|
|
<hr />
|
|
<h1><a name="return_values">RETURN VALUES</a></h1>
|
|
<p><code>BN_cmp()</code> returns -1 if <strong>a</strong> < <strong>b</strong>, 0 if <strong>a</strong> == <strong>b</strong> and 1 if
|
|
<strong>a</strong> > <strong>b</strong>. <code>BN_ucmp()</code> is the same using the absolute values
|
|
of <strong>a</strong> and <strong>b</strong>.</p>
|
|
<p><code>BN_is_zero()</code>, <code>BN_is_one()</code> <code>BN_is_word()</code> and <code>BN_is_odd()</code> return 1 if
|
|
the condition is true, 0 otherwise.</p>
