intBYTES 用于表示double值的字节数。 intMAX_EXPONENT 变量可能具有的最大指数有限double。 doubleMAX_VALUE 的常量保持型的最大正的有限值double,(2-2-52)A·21023。 intMIN_EXPONENT 一个归一化的double变量可能有的最小指数。 doubleMIN_NORMAL 常数保持double-1022的最小正常正常值。
double转bytes 技术标签: java 安卓首先,我们要了解一下double数据在内存中是如何存储的: 1位符号+11位阶码+53位尾数 符号位:整数位0,负数为1; 阶码:阶码 = 阶码真值 + 偏移量 1023。偏移量 = 2^(k-1)-1,k表示阶码位数; 尾数:数字的小数部分。 举个栗子: 十进制 -125.125,在JS内存中的二进制数据是...

For any result-bit to be “1,” the respective bits in both arguments must be “1.” Notice in this example that the argument on top contains all zeroes in the high-order bytes and all ones in the low-order byte. The effect on the second argument in this example is that the low-...

Not really ariel, it has more to do with how many bytes thr number will occupy in memory. A single precision floating point number takes 4 bytes of space in memory. This is enough for normal operations where decimals are needed. But, for operations where a lot more precision is needed,...
