numerator词源中文解释
“分子，分母的上部或上方所标示的数值”，1540年代即是“用于表示某物数量的单词或数字符号”（现已过时），源自于“计数器，数数人”的拉丁语 numerator，是 numerat- 的代理人名词， numerat- 是 numerare 的过去分词词干，意为“计数，编号”，其中 numerus 表示“数字”（参见 number）。自1570年代以来，“分数线上方写下的数值”，到了1670年代，“进行计数的人或事物”也被称为“numerator”。

numerator词源英文解释
borrowed from Middle French & Late Latin; Middle French numerateur, borrowed from Late Latin numerātor "counter, enumerator," from Latin numerāre "to count, number >entry 2" + -tor, agent suffix Note: The Middle French word numerateur (modern numérateur) as a name for the part of a fraction above the line was probably introduced into European mathematical terminology by the mathematician Estienne de La Roche (ca. 1470-ca. 1530), who used it in Larismethique nouellement composee (Lyon, 1520). It is now known that La Roche adopted numerateur as well as denominateur denominator from an earlier mathematician of Lyon, Nicolas Chuquet (ca. 1445-55-1488 or later). Chuquet introduced the words in his Triparty en la science des nombres ("The Science of Numbers in Three Parts"), the manuscript of which dates to 1485, though it was not published until 1880.
The first known use of numerator was in 1539
