1. JavaScript的数字 JavaScript数字全部是浮点数。 根据 IEEE 754标准中的64位二进制(binary64), 也称作双精度规范(double precision)来储存。从命名中可以看出,这些数字将以二进制形式,使用64个位(感谢jingge指出错误)来存储。这些字节按照以下规则分配:
Looking at the row (p=53), it should be obvious that JavaScript numbers can have bit 53 set to 1. But as the fraction f only has 52 bits, bit 0 must be zero. Hence, only even numbers x can be represented in the range 253≤ x < 254. In row (p=54), that spacing increases ...
