Returns a BigDecimal whose value is (this × multiplicand), and whose scale is (this.scale() + multiplicand.scale()) .

Usage

From source file:Main.java

public static double mul(double d1, double d2) {
    BigDecimal bd1 = new BigDecimal(Double.toString(d1));
    BigDecimal bd2 = new BigDecimal(Double.toString(d2));
    return bd1.multiply(bd2).doubleValue();
}

From source file:Main.java

public static Double mul(Double v1, Double v2) {
    BigDecimal b1 = new BigDecimal(v1.toString());
    BigDecimal b2 = new BigDecimal(v2.toString());
    return Double.valueOf(b1.multiply(b2).doubleValue());
}

From source file:Main.java

public static double mul(double v1, double v2) {
    BigDecimal b1 = new BigDecimal(Double.toString(v1));
    BigDecimal b2 = new BigDecimal(Double.toString(v2));

}

From source file:Main.java

public static Double mul(Double v1, Double v2) {
    BigDecimal b1 = new BigDecimal(Double.toString(v1));
    BigDecimal b2 = new BigDecimal(Double.toString(v2));
    double m = b1.multiply(b2).doubleValue();
    return m;/*  w w  w.j a v a 2  s .  c  o  m*/
}

From source file:Main.java

public static double mul(double value1, double value2) {
    BigDecimal b1 = new BigDecimal(Double.valueOf(value1));
    BigDecimal b2 = new BigDecimal(Double.valueOf(value2));
    return b1.multiply(b2).doubleValue();
}

From source file:Main.java

    BigDecimal b1 = new BigDecimal(Float.toString(v1));

    BigDecimal b2 = new BigDecimal(Float.toString(v2));

    return b1.multiply(b2).floatValue();

}

From source file:Main.java

    String result = "0";

    if (number != null) {
        number = number.multiply(new BigDecimal("100"));
        DecimalFormat formatter = new DecimalFormat();
        formatter.setMaximumFractionDigits(fractionDigit);
        formatter.setMinimumFractionDigits(fractionDigit);

        result = formatter.format(number);
    }//from w w  w.  j a  v a 2s . c  o  m
    return result;
}
