Dataweave始终输出带有两位小数的JSON编号 [英] Dataweave Always output JSON number with two decimal places

问题描述

我在Dataweave中通过xml输入了以下数字.

I've got the following number coming through via xml in Dataweave.

<b:AmountValue>180.90</b:AmountValue>

使用Dataweave，我试图输出一个带有两个小数位(代表货币)的json编号.

Using Dataweave I am trying to output a corresponding json number with two decimal places (to represent currency).

这是我的Dataweave表达式的样子...

Here is what my Dataweave expression looks like...

amount: $.AmountValue as :number as :string {format: ".00"} as :number

输出json丢失尾随零.

The output json is losing the trailing zero.

i.e. "amount":180.9 

如何将Dataweave表达式更改为始终有两个小数位?

How can I change my Dataweave expression to always have two decimal places?

或者也许我误解了json数字类型?

Or perhaps I'm misunderstanding the json number type?

谢谢

推荐答案

如果可以将金额作为字符串使用，则删除最后一个as :number

remote the last as :number if you can live with amount being a string

amount: $.AmountValue as :number as :string {format: ".00"}
