1 英语沸腾
实数:Real number
2 英文阐明
2.1 What is a Real number?
八月未央 自慰A real number is any number that can be placed on a number line or expressed as in infinite decimal expansion. In other words, a real number is any rational or irrational number, including positive and negative whole numbers, integers, decimals, fractions, and numbers such as pi (π) and Euler’s number (e).
实数是不错放在数字线上或以无尽十进制张开暗意的任何数字。换句话说,实数是任何有理数或乖僻数,包括正负整数、整数、少许、分数和数字,举例 pi (π) 和欧拉数 (e)。
In contrast, an imaginary number or complex number is not a real number. These numbers contain the number i, where i² = -1.
相背,虚数或复数不是实数。这些数字包含数字 i,其中 i² = -1。
Real numbers are represented by the capital letter “R” or double struck typeface . The real numbers are an infinite set of numbers.
2.2 Why are they called \"Real\" Numbers?
Because they are not Imaginary Numbers.
因为它们不是虚数。
The Real Numbers had no name before Imaginary Numbers were thought of. They got called \"Real\" because they were not Imaginary. That is the actual answer!
在虚数出现之前,实数是没闻明字的。它们被称为“确实”,因为它们不是诬捏的。这才是着实的谜底!
3 中语阐明
实数,是有理数和乖僻数的总称。
要思长远交融这些专科术语,一定要看英语甘愿啊,明明阳春白雪的英语词语,翻译成中语之后就变得晦涩难解。
