1.For instance, if you assign an integral value to a floating-point variable, the compiler will automatically convert the int to a float.
例如，假设我们为浮点变量分配一个整数值，计算机会将int自动转换成float。
3.if you multiply a float and a double, the result will be double;
若将一个float值与一个double值相乘，结果就是double；
4.So the answer is that casting from a float or double to an integral value always truncates.
所以答案就是: 将一个float或double值造型成整数值后，总是将小数部分“砍掉”，不作任何进位处理。
5.Upper or lowercase L means long, upper or lowercase F means float and upper or lowercase D means double.
若为大写或小写的L，代表long；大写或小写的F，代表float；大写或小写的D，则代表double。
6.That is, you can do anything with a BigInteger or BigDecimal that you can with an int or float, it’s just that you must use method calls instead of operators.
也就是说，能对int或float做的事情，对BigInteger和BigDecimal一样可以做。只是必须使用方法调用，不能使用运算符。
7.the compiler normally takes exponential numbers as doubles, so without the trailing f it will give you an error telling you that you must use a cast to convert double to float.
编译器通常会将指数作为双精度数(double)处理，所以假如没有这个尾随的f，就会收到一条出错提示，告诉我们须用一个“造型”将double转换成float。
8.The first thing you will see are some shorthand methods for printing: the prt( ) method prints a String, the pInt( ) prints a String followed by an int and the pFlt( ) prints a String followed by a float.
我们注意到的第一件事情就是用于打印(显示)的一些快捷方法: prt()方法打印一个String；pInt()先打印一个String，再打印一个int；而pFlt()先打印一个String，再打印一个float。
9.Free float says again " clean float " , show central bank does not take any interpose activities to foreign currency market, exchange rate is decided initiatively completely by market strength; Administrative float says again " dirty float " , point to the country that executes floating rate to make, the wave motion of its central bank for control or exchange rate of slow down market, have multiform interpose activity to foreign currency market, basically be a basis the circumstance work off of foreign currency market or purchase foreign currency, affect exchange rate in order to pass to the influence of supply and demand.
自由浮动又称“清洁浮动”，指中心银行对外汇市场不采取任何干预活动，汇率完全由市场力量自发地决定；治理浮动又称“肮脏浮动”，指实行浮动汇率制的国家，其中心银行为了控制或减缓市场汇率的波动，对外汇市场进行各种形式的干预活动，主要是根据外汇市场的情况售出或购入外汇，以通过对供求的影响来影响汇率。
10.Abstract: Based on the research of the three-dimensional models of glass batch,molten glass flow and heat transfer within glass furnaces,the result of graphic simulation of temperature and velocity fields are given.By comparison with the erosion refractory photos in the cold state of 300 T/d float furnace of Hangzhou Float Glass Industry Ltd.,the reliability of the models is proved.At the same time,the effect of glass temperature and velocity fields distribution on erosion of refractory with in float glass furnace are discussed.
文摘:通过对窑内配合料及玻璃液流运动和传热的三维数学模型研究，对玻璃液温度场和流场进行了图形模拟，将模拟结果与杭州浮法玻璃工业有限公司300吨级浮法窑冷修时所拍摄的各部位耐火材料被侵蚀情况照片进行了比较、分析，验证了模型的可靠性，并分析耐火材料的被侵蚀与玻璃液温度场和流场分布的影响。
