BigDecimal 加减乘除运算[通俗易懂]

BigDecimal n1 = new BigDecimal("0.01");
BigDecimal n2 = new BigDecimal("0.02");

System.out.println("加法:"+n2.add(n1));


加法:0.03

 BigDecimal n1 = new BigDecimal("0.01");
 BigDecimal n2 = new BigDecimal("0.02");
System.out.println("减法:"+n2.subtract(n1));

减法:0.01

 BigDecimal n1 = new BigDecimal("0.01");
 BigDecimal n2 = new BigDecimal("0.02");

System.out.println("乘法:"+n2.multiply(n1));

乘法:0.0002

BigDecimal n1 = new BigDecimal("0.01");
BigDecimal n2 = new BigDecimal("0.02");

 System.out.println("除法:"+n2.divide(n1));

除法:2

BigDecimal n3 = new BigDecimal("-0.09");

 System.out.println("绝对值:"+n3.abs());

绝对值:0.09
