在Java中,我们可以使用Double类中的常量POSITIVE_INFINITY和NEGATIVE_INFINITY来表示正无穷大和负无穷大。 正无穷大和负无穷大的表示 在Java中,正无穷大和负无穷大可以通过Double类中的常量来表示。具体的表示如下: 正无穷大:Double.POSITIVE_INFINITY 负无穷大:Double.NEGATIVE_INFINITY 这两个常量可以用于表示数学计算中的...
If the argument is positive infinity, then the result is positive infinity. If the argument is positive zero or negative zero, then the result is negative infinity. If the argument is equal to 10n for integer n, then the result is n. The computed result must be within 1 ulp of the...
* If the argument is NaN or an infinity or positive zero or negative * zero, then the result is the same as the argument. * If the argument value is less than zero but greater than -1.0, * then the result is negative zero. * * Note that the value of {@code Math.floor(x)} ...
在Java中,Math.log()方法用于计算一个数的自然对数。它遵循以下规则处理特殊值: 如果参数是负数或零,Math.log()方法将返回负无穷大(Double.NEGATIVE_INFINITY)。 如果参数是正无穷大(Double.POSITIVE_INFINITY),Math.log()方法将返回正无穷大(Double.POSITIVE_INFINITY)。 如果参数是NaN(Not-a-Number),Math.log()...
* If the argument is negative infinity or any value less than or * equal to the value of {@codeLong.MIN_VALUE}, the result is * equal to the value of {@codeLong.MIN_VALUE}. * If the argument is positive infinity or any value greater than or * equal to...
