如果算式,减号后面有空格,是不会遇到这个问题的。现在已经修正。
原因是因为-2有时候要理解成 “负2”, 有时候要理解成“减2”,如果减号前面是个数字,百分号和阶乘号,那说明它是个“减” 如果减号前面是其它运算符号,那它就是“负” 。
其它符号没有这个转换问题,Unit test里没有使用减法。。。所以。。。。
现在增加了三行减法UT

        expect(rpn.rpnCalculate(rpn.infix2rpn('5-1'))).equal(4);
        expect(rpn.rpnCalculate(rpn.infix2rpn('5+ -2'))).equal(3);
        expect(rpn.rpnCalculate(rpn.infix2rpn('5--2'))).equal(7);

from rpn.js.
