例如,业务用户可能不知道double表示双精度小数。
For example, a business user might not know that double means a double-precision decimal.
它们都依据IEEE 754标准,该标准为32位浮点和64位双精度浮点二进制小数定义了二进制标准。
These are based on the IEEE 754 standard, which defines a binary standard for 32-bit floating point and 64-bit double precision floating point binary-decimal Numbers.
其中一个构造函数以双精度浮点数作为输入,另一个以整数和换算因子作为输入,还有一个以小数的String表示作为输入。
One takes a double-precision floating point as input, another takes an integer and a scale factor, and another takes a String representation of a decimal number.
