Either expression is a floating - point data type 每个表达式都是浮点数据类型(
Is not a floating - point data type 不是浮点数据类型。
Is not a floating - point data type 不是浮点数据类型)
The floating - point data types do not have any internal representation of trailing 0 characters 浮点数据类型没有尾随0字符的任何内部表示形式。
The nullability property of arithmetic operators over floating point data type is always nullable 对浮点数据类型执行运算的算术运算符的为空性属性始终可为空。
The nullability property of arithmetic operators over the floating point data type is changed to nonnullable for the case where the inputs are nonnullable and ansi warnings is on 在输入不可为空并且ansi _ warnings为on的情况下,对浮点数据类型执行运算的算术运算符的为空性属性将更改为不可为空值。
Because the calculation involves floating - point data types that are represented in memory by less than 80 bits , however , carrying the extra bits of precision 80 bits minus the number of bits in a smaller floating - point type through a lengthy calculation can produce inconsistent results 然而,由于计算涉及浮点数据类型(在内存中用少于80位表示) ,在冗长计算中进位多余精度位( 80位减去较小浮点型的位数)会产生不一致的结果。
