Examples of org.bouncycastle2.math.ec.SimpleBigDecimal

org.bouncycastle2.math.ec.ECCurve
Class representing a simple version of a big decimal. A SimpleBigDecimal is basically a {@link java.math.BigInteger BigInteger} with a few digits on the right ofthe decimal point. The number of (binary) digits on the right of the decimal point is called the scale of the SimpleBigDecimal. Unlike in {@link java.math.BigDecimal BigDecimal}, the scale is not adjusted automatically, but must be set manually. All SimpleBigDecimals taking part in the same arithmetic operation must have equal scale. The result of a multiplication of two SimpleBigDecimals returns a SimpleBigDecimal with double scale.
