Examples of java.math.BigDecimal.movePointLeft()

java.math.BigDecimal.movePointLeft()
Returns a {@code BigDecimal} which is equivalent to this onewith the decimal point moved {@code n} places to the left. If{@code n} is non-negative, the call merely adds {@code n} tothe scale. If {@code n} is negative, the call is equivalentto {@code movePointRight(-n)}. The {@code BigDecimal}returned by this call has value (this × 10^-n) and scale {@code max(this.scale()+n,0)}. @param n number of places to move the decimal point to the left. @return a {@code BigDecimal} which is equivalent to this one with the decimal point moved {@code n} places to the left. @throws ArithmeticException if scale overflows.

        int nanos = value.getNanos();
