Examples of java.math.BigDecimal.negate()

java.math.BigDecimal.negate()
Returns a {@code BigDecimal} whose value is {@code (-this)}, and whose scale is {@code this.scale()}. @return {@code -this}.

                final BigDecimal v = BigDecimalMath.sqrt( l.subtract(re).divide(half,mc), mc );

                        return new BigComplex(u,v) ;
                else
                        return new BigComplex(u,v.negate()) ;
