百億閻浮（此三千大千世界之內合有百億依經說億有三種數法不同若依下數十萬為億計有萬億數有餘也若依上數萬萬為億只有十億數不足今依華嚴經一百洛叉為一億故有百億也）。

"One hundred million Jambudvīpas" (Within this trichiliocosm, there are altogether one hundred million. According to what the sūtras say, there are three systems of reckoning "billion" (億) that differ: if according to the lower reckoning of one hundred thousand as a billion, then reckoning would yield ten thousand billion, which is an excess; if according to the upper reckoning of one hundred million as a billion, there would be only ten billion, which is insufficient. Now, following the Avataṃsaka-sūtra, one hundred lakṣas make one koṭi (億), and hence there are one hundred million).
