real number

On the other hand, floating types have density much smaller than 1, which means that there are real numbers unrepresented between consecutive floating values (i.e. there are gaps).

另方面，浮点类型的密度远小于1，着相邻的浮点值之间存无法表示的实数(即有定间隙)。

In the real numbers are chosen in such a way that the probability that the number lies in any particular subinterval of this unit interval is equal to the length of the subinterval.

实数被选择，种情况下可能性数字谎个单位信号间隔所有特殊子区间与子区间的长度是相等的。
