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(
A floating - point division returns 浮点数除法返回
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。
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
