exponent 指数,阶 In a floating-point representation, the numeral that denotes the power to which the implicit floating-point base is raised before being multiplied by the fixed- point part to determine the real number represented, for example, a floating- point representation of the number 0.0001234 is 0.1234-3, where 0.1234 is the fixed-point part and -3 is the exponent. 浮点表示法中表示幂的数字。将隐含的浮点基数按此幂自乘后再乘以定点部分, 即求得用浮点表示法所表示的实数。例如,数0.0001234的浮点表示为0.1234-3, 其中0.1234是定点部分,-3是指数。 |
