double-precision

常見例句

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(shù)，用 11 位表示指數(shù)，52 位表示尾數(shù)。
One takes a double-precision floating point as input, another takes an integer and a scale factor, and another takes a String representation of a decimal number.
其中一個搆造函數(shù)以雙精度浮點數(shù)作爲輸入，另一個以整數(shù)和換算因子作爲輸入，還有一個以小數(shù)的 String 表示作爲輸入。
The DOUBLE type can also be referred to as DOUBLE PRECISION, although it isn't clear why you would want to type the extra word every time you need a double-precision number.
DOUBLE 類型也可以表示爲 DOUBLE PRECISION，雖然爲什麼在需要雙精度數(shù)字時要輸入額外的單詞，原因不明。
