mantissa

常见例句

For double-precision floating point, 11 bits are dedicated to the exponent and 52 bits to the mantissa.
(2 -2)，依此类推。对于双精度浮点数，用 11 位表示指数，52 位表示尾数。
Doubles are encoded in much the same way except that they use a 52-bit mantissa and an 11-bit exponent for higher precision.
双精度数是以类似的方式编码的，但是它使用 52 位的尾数和 11 位的指数来获得更高的精度。
With some effort, you could separately find the mantissa, take its log, and add that value to the exponent, but that's hardly worth the effort.
通过一些步骤，就可以找到尾数、取尾数的对数并将该值添加到指数，但这有些费劲。
