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