Examples of java.math.BigDecimal.longValueExact()

java.math.BigDecimal.longValueExact()
Converts this {@code BigDecimal} to a {@code long}, checking for lost information. If this {@code BigDecimal} has anonzero fractional part or is out of the possible range for a {@code long} result then an {@code ArithmeticException} isthrown. @return this {@code BigDecimal} converted to a {@code long}. @throws ArithmeticException if {@code this} has a nonzerofractional part, or will not fit in a {@code long}. @since 1.5

            // Strip off fraction part by converting via BigInteger
            // lest longValueExact will throw ArithmeticException
            BigDecimal tmp = new BigDecimal(
                getBigDecimal(buffer, offset, precision, scale).toBigInteger());
            // throws ArithmeticException if overflow:
            return tmp.longValueExact();
        }
    }
