实数

Integers, rational numBers, and ir rational numBers are all real.

整数、有理数和无理数都是实数。

0 In the set of rational numbers can be worked out with , how can we solve the problem about the equation x 2＋1 = 0 without solution in the set of real numbers?

类比引进就可以解决方程 x 2－2=0在有理数集中无解的问题，怎么解决方程 x 2＋1=0在实数集中无解的问题？

Consider the set of all rational numbers.

当考虑所有有理数的集合时，有些门外汉可能会天真地认为有理数理所当然地多於整数，而有理数又显然少於实数，因此把连续统假设证否。

Rational numbers and irrational numbers together form the set of real numbers.

有理数与无理数一起构成实数。

Extend atof to handle scientific notation of the form 123.45e-6 where a floating-point number may be followed by e or E and an optionally signed exponent.

解：会处理普通实数字符串同样也要会处理科学记数法的，这里就是让我们干这个，很简单其实，前面用atof后面如果有e或者E用atoi，最后一组合就是答案

On the other hand, it is beyond question that, owing to the determining influence of Origen and the Platonic philosophy, which, as is well known, attached but slight value to visible matter and the sensible phenomena of the world, Augustine did not refer what was properly real in the Blessed Sacrament to the Flesh of Christ, but transferred it to the quickening principle, ie to the effects produced by a worthy Communion.

在另一方面，这是毫无疑问的是，由於决定性的影响渊源和柏拉图哲学，其中，因为是众所周知的，但附加价值轻微，以有形此事，并有理智的现象世界，奥古斯丁没有提到什麼是恰当的实数，在圣体，以耶稣的身体，但它转移到加快原则，即所产生的效果由一个值得共融。

In this paper the writer employs complex Riemannian Geometry and defines the absolute interval between two points as consisting of a real part and an imaginary part. Two postulates and are used: the first may be called law of gravitation and electro-magnetism; the second equation of motion.

在此文内，作者利用复变来曼几何以宇宙间两点之距离为一实数及一虚数部分相构而成，於此并用假说：一可称为吸力及电磁定律，一为物体行动定律，解释吸力及电磁力之各种现象。
