(3).从 20——99 整数几十中除twenty,thirty, forty,fifty,eighty为特殊形式外,sixty,seventy,ninety都是其个位数形式后添加后缀-ty构成。表示几十几时,在几十和个位基数词形式之间添加连字符“-” 21 twenty-one 76 seventy-six (4).百位数个数基数词形式加“hundred”,表示几百,在几十几与百位间加上and.

(5).千位数以上从数字的右端向左端数起,每三位数加一个逗号“,”。从右开始,第一个“,”前的数字后添加 thousand,第二个“,”前面的数字后添加 million,第三个“,”前的数字后添加 billion。然后一节一节分别表示,两个逗号之间最大的数为百位数形式。
