我必须操控小数计算。 所有的数据都已经在客户端, 操作正在因用户互动( 选择) 而改变。 因此我当然可以访问服务器, 以适应每个用户选择的变化, 但这需要花费时间和额外的复杂性 。
我开始在客户端操作小数计算,并抛出全球化分析问题。 我还担心服务器端的小数计算可能与客户端处理结果不相等。
所以简单的计算服务器侧的十进制值更好, 还是仅仅为显示目的通过 JavaScript 进行计算没有问题?

首先,在处理货币问题时,ALWAYS用整数工作。如果用美元工作,乘以100,用美分工作。不管你用什么货币,用最小值的单位工作。
这将消除任何四舍五入错误的可能性。
只有在你拥有了最后的硬币价值之后,再除以100(或最好使用字符串操纵),才能非常精确地展示。
这将保证客户和服务器获得同样的结果。
就像问科学计算器是否比正常计算器更好,
是的,它很好,但要谨慎行事。 联署材料对不精确的十进制有一个已知问题。 据我所知,人们用“分数 ” ( Integers)计算,然后用“美元”(浮点/十进制)除以100。
当然,你也应该在事后进行验证,因为人们普遍知道,人们决不能轻易相信客户方的投入。
