2 * Some BIGNUM functions assume most significant limb to be non-zero, which
3 * is customarily arranged by bn_correct_top. Output from below functions
4 * is not processed with bn_correct_top, and for this reason it may not be
5 * returned out of public API. It may only be passed internally into other
6 * functions known to support non-minimal or zero-padded BIGNUMs.
