Operator to perform floating - point division 运算符执行浮点除法。
Multiplication and floating - point division 乘法和浮点除法(
Data type , no exception is thrown , and the result is the class member representing 数据类型的浮点除法运算中,不会引发异常,运算结果为表示
1 . the division operator is overloaded to handle both integer and floating - point division , depending on the operands 1 .根据操作数,除法运算符被重载以便处理整数除法和浮点除法。
Do the design methodology and development tools we use today will meet the need of design abstraction after raising the design level ? the answer is probably not . on the another hands , because of the increase in complexity of hardware , the subtle errors is much greater 1994年intel公司的pentium芯片中的浮点除法运算错误是在其大量进入商用后才被一位用户发现的,虽然这种错误发生的概率为几亿分之一。
The div operator performs floating - point division , the mod operator returns the remainder from a truncating division . the floor function returns the largest closest to positive infinity number that is not greater than the argument and that is an integer . the ceiling function returns the smallest closest to negative infinity number that is not less than the argument and that is an integer Div运算符做浮点除法运算, mod运算符做求余运算, floor函数返回不大于参数的最大整数趋近于正无穷, ceiling返回不小于参数的最小整数趋近于负无穷
On the one hand it is important for the design of floating - point processor unit to optimize speed while algorithms of high - speed are introduced . for examples , two - path of high - speed floating - point addition , booth coding of floating - point multiplication . srt of floating - point division and square root , cordic of transcendental function and so on 一方面浮点处理部件设计重点在于速度的优化,所以采用优化的高速算法,如浮点加法的two - path 、浮点乘法的booth编码、浮点除法和平方根的srt算法以及超越函数的cordic算法等。
