查询词典 float

Compared to the built-in float implementation of binary floating point, the new class is especially helpful for financial applications and other uses which require exact decimal representation, control over precision, control over rounding to meet legal or regulatory requirements, tracking of significant decimal places, or for applications where the user expects the results to match calculations done by hand.

相比内置的二进制浮点数实现：class：' float'，新类型特别适用于金融应用和其它需要精确十进制表达的场合，控制精度，控制舍入以适应法律或者规定要求，确保十进制数位精度，或者用户希望用作数学计算的场合。

So e 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。

If one of the numbers are of the type float or of type double , floating point math will be used for the calculation.

如果操作数的数据类型是 float 或者 double ，那么就会以浮点来进行计算。

The main reason for using float is to save storage in large arrays, or, less often, to save time on machines where double-precision arithmetic is particularly expensive.

使用float类型主要是为了在使用较大的数组时节省存储空间，有时也为了节省机器执行时间(双精度算术运算特别费时)。

If the name is followed by an equals sign and an expression, the expression serves as an initializer, as in char esc ='\\'; int i = 0; int limit = MAXLINE+1; float eps = 1.0e-5

在声明中，如果变量名的后面紧跟一个等号及一个表达式，该表达式就充当对变量进行初始化的初始化表达式。例如： char esc ='\\'； int i = 0； int limit = MAXLINE+1； float eps = 1.0e-5
