es6改变数组对象key对应的值

let arr = [
    {
        a:'13',
        b:'b1',
        d:'d1'
    },
    {
        a:'13',
        c:'c1'
    }
]

怎么把数组对象中所有key为a的值除以100,变成如下

let arr = [
    {
        a:'0.13',
        b:'b1',
        d:'d1'
    },
    {
        a:'0.13',
        c:'c1'
    }
]

arr.forEach(item => item.a /=100);
