加减乘除demo

// 0.1＋0.2
math.format(math.chain(math.bignumber(0.1)).add(math.bignumber(0.2)).done());
 
// 0.2-0.1
math.format(math.chain(math.bignumber(0.2)).subtract(math.bignumber(0.1)).done());
 
// 0.1*0.2
math.format(math.chain(math.bignumber(0.1)).multiply(math.bignumber(0.2)).done());
 
// 0.1/0.2
math.format(math.chain(math.bignumber(0.1)).divide(math.bignumber(0.2)).done());
