Compare if BigDecimal is greater than zero
It's as simple as:
if (value.compareTo(BigDecimal.ZERO) > 0)The documentation for compareTo actually specifies that it will return -1, 0 or 1, but the more general Comparable<T>.compareTo method only guarantees less than zero, zero, or greater than zero for the appropriate three cases - so I typically just stick to that comparison.
if (value.signum() > 0)signum returns -1, 0, or 1 as the value of this BigDecimal is negative, zero, or positive.
