Instead, in exceptional situations the result of a floating-point operation is zero, infinity, or NaN, as described below: If the result of a floating-point operation is too small for the destination format, the result of the operation is zero. If the magnitude of the result of a floating...

doublea=1.0;doubleb=0.0;doublec=a/b;// 结果为正无穷大doubled=b/b;// 结果是NaNSystem.out.println(c);// 输出InfinitySystem.out.println(d);// 输出NaN 1. 2. 3. 4. 5. 6. 7. 在上面的示例中,我们进行了两个除法运算。在第一个除法运算中,我们将a除以b,结果为正无穷大。在第二个除法...
首先你知道double是8个字节,然后你得知道double的内存存储结构 低52位是底数,这里全用1填充 再11位是指数,11位指数可表示-1024~1023,规定统统加上1023,所以指数这里填充2046的bit位 最高位是符号为,为0表示+ 测试代码如下:include <stdio.h> //for printf#include <string.h>//for memcpy#...

傳回值可以是 PositiveInfinitySymbol、 NegativeInfinitySymbol、 NaNSymbol或數位的字串表示,如所 format指定。 參數format 可以是 D 和 X 以外的任何有效標準數值格式規範,以及自定義數值格式規範的任何組合。 如果 為 formatnull 或空字串,則傳回值會使用一般數值格式規範來格式化, (“G”) 。 .NET 提供廣泛的...
