Examples of java.math.BigDecimal.divide()

java.math.BigDecimal.divide()
Returns a {@code BigDecimal} whose value is {@code (this /divisor)}, with rounding according to the context settings. @param divisor value by which this {@code BigDecimal} is to be divided. @param mc the context to use. @return {@code this / divisor}, rounded as necessary. @throws ArithmeticException if the result is inexact but therounding mode is {@code UNNECESSARY} or {@code mc.precision == 0} and the quotient has a non-terminating decimal expansion. @since 1.5
