Add Compare method which forwards calls to Cmp ( #346 )
...
Given the interface definition
type Ordered[T any] interface {
Compare(T) int
}
And the type constraint T Ordered[T], make decimal.Decimal satisfy this
constraint, so that generic code written against T Ordered[T] can work
with decimal values as smoothly as it works with time.Time values today.
Fixes : #345

Fix decoding of .0
...
Since trailing 0 digits after the decimal point are trimmed, intString
becomes an empty string when there is no digit before the decimal point
and all digits after the decimal point is 0, causing big.Int SetString
to fail because there is no string to parse.
Fix #134 .
