And there you have it – quick and to the point examples of how to generate both unbounded and bounded values for the most common numerical primitives in Java. 9. Conclusion This tutorial illustrated how we could generate random numbers either bound or unbound, using different techniques and lib...

Unlike {@link * #compareTo(BigDecimal) compareTo}, this method considers two * {@code BigDecimal} objects equal only if they are equal in * value and scale (thus 2.0 is not equal to 2.00 when compared by * this method). * 该方法认为两个BigDecimal对象只有在值和比例相等时才相等,所以当...

The results of this constructor can be somewhat unpredictable. One might assume that writing new BigDecimal(0.1) in Java creates a BigDecimal which is exactly equal to 0.1 (an unscaled value of 1, with a scale of 1), but it is actually equal to 0.100000000000000005551115123125782702118158340454101562...
