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)，依此類推。對於雙精度浮點數，用 11 位表示指數，52 位表示尾數。
Doubles are encoded in much the same way except that they use a 52-bit mantissa and an 11-bit exponent for higher precision.
雙精度數是以類似的方式編碼的，但是它使用 52 位的尾數和 11 位的指數來獲得更高的精度。
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.
通過一些步驟，就可以找到尾數、取尾數的對數竝將該值添加到指數，但這有些費勁。
