小数(decimal)的概述：
小数点读作point，小数点左边按整数的基数词(one,two,three...)读，小数点右边依次用个位数的基数词读出。整数部分为零时，小数点可以省略不读。当小数大于1时，小数后面的名词用复数，小数小于1时，小数后面的名词用单数。
| 数字 | 表示法 |
| 0.4 | naught O zero point four; point four |
| 0.128 | naught O zero point one two eight; point one two eight |
| 0.305 | naught O zero point three o five; point three zero five |
| 数字 | 表示法 |
| 5.02 | five point naught O zero two; five point o two |
| 8.004 | eight point naught naught O zero zero four; eight point o o four |
| 33.33 | thirty-three point three three |
| 数字 | 表示法 |
| 8.3万 | (83,000) eighty-three thousand |
| 723.64万 | (7,236,400) seven mil-lion, two hundred and thirty-six thousand, four hundred |
| 17.03亿 | (1,703,000,000) one point seven o three billion; one billion, seven hundred and three million |
小数的读法：
小数点读作point，小数点左边按整数的基数词（one, two, three...）读，小数点右边依次用个位数的基数词读出。整数部分为零时，小数点可以省略不读。当小数大于1时，小数后面的名词用复数，小数小于1时，小数后面的名词用单数。
1、小于"1"的小数：
小数点左边的零读做naught（英）或zero（美），也可不在小数点后遇到零时，可读做naught或zero，也可以读做字母"o"的音，例如：
| 数字 | 表示法 |
| 0.4 | zero point four; point four |
| 0.456 | zero point four five six; point four five six |
| 0.213 | zero point two one three; point two one three |
| 数字 | 表示法 |
| 4.51 | four point five one; |
| 2.005 | two point zero zero five; two point o o five |
| 19.11 | nineteen point one one |
| 数字 | 表示法 |
| 5.6万 | fifty-six thousand (56,000) |
| 765.48万 | seven million, six hundred and five-four thousand, eight hundred (7,654,800) |
| 17.03亿 | one point seven o three billion; one billion, seven hundred and three million (1,703,000,000) |
