1·Scan out the fraction part as a string.
扫描出一部分作为字符串的一部分。
2·The integer part, the optional decimal point and the optional fraction part form the significant part of the floating literal.
整数部分，可选的小数点，以及可选的小数部分组成浮点文字量的有效部分。
3·But we don't normally write hours with decimal points. Floor division returns the integer number of hours, dropping the fraction part.
不过一般咱们不写有小数的小时数。地板除法返回的就是整的小时数，舍弃掉小数位。
4·A floating literal consists of an integer part, a decimal point, a fraction part, ane or e, an optionally signed integer exponent, and an optional type suffix.
浮点文字量由整数部分，小数点，小数部分，e或e，可选的有符号整数指数，以及可选的类型后缀组成。
5·However using light to find one's own way around requires vastly more energy, since the eyes have to detect the tiny fraction of the light that bounces off each part of the scene.
然而，利用光来找到自己的方向极大地需要更多的能量，因为眼睛必须检测从场景的每个部分反射的光的极小部分。
6·For floating-point Numbers, you place a decimal as the separator between the whole part of the number and the fraction.
对于浮点数，您将在整数部分和小数部分之间放置小数点。
7·However, using light to find one’s own way around requires vastly more energy, since the eyes have to detect the tiny fraction of the light that bounces off each part of the scene.
但是，眼睛必须去识别周围景象反射的细微光线，所以若要用光线来探路就需要远远比这多的能量了。
8·Visual acuity - As part of the testing, you'll be asked to read letters on a distance chart. This test measures visual acuity, which is written as a fraction such as 20/40.
视觉灵敏度检测——作为视力检测的组成部分，你需要读出视力表上的字母以测出你的视觉灵敏度，它可以写成分数的形式，比如20/40。
9·Regression results showed that reaction time, pressure and composition of feed gas had marked effects on mass fraction of xylene soluble part and ethylene content in copolymer.
实验结果表明，反应压力、反应时间、原料气中乙烯含量对共聚物中的乙烯含量、二甲苯可溶物含量有显著影响；
10·Construction cost constitutes only a fraction, though a substantial fraction, of the total project cost. However, it is the part of the cost under the control of the construction project manager.
建造成本是整个项目成本中的一部分，虽然很重要，但只是施工项目经理控制下的成本的一部分。
