格式化浮点数而不AngularJS precision损失 [英] Formatting floating-point numbers without loss of precision in AngularJS
问题描述
在AngularJS如何在HTML页面中做I输出一个浮点数，而不precision的损失和避免不必要的填充与0？
In AngularJS how do I output a floating point number on an HTML page without loss of precision and without unnecessary padding with 0's?
我认为是数字NG-过滤器（ https：//开头的文档。 angularjs.org/api/ng/filter/number ），但fractionSize参数导致固定数量的小数位数：
I've considered the "number" ng-filter (https://docs.angularjs.org/api/ng/filter/number) but the fractionSize parameter causes a fixed number of decimals:
{{ number_expression | number : fractionSize}}
我在寻找各种其他语言的东西被称为精确的重现，规范化字符串重新presentation，再版，往返等，但我一直没能找到任何东西类似的AngularJS。
I'm looking for what in various other languages is referred to as "exact reproducibility", "canonical string representation", repr, round-trip, etc. but I haven't been able to find anything similar for AngularJS.
例如：
- 1 =>1
- 1.2 =>1.2
- 1.23456789 =>1.23456789
推荐答案
我偶然发现了一个明显的解决方案喽！完全删除使用数字NG-过滤器会导致AngularJS根据我的要求除权pression简单地转换为字符串。
I stumbled upon an obvious solution myself! Completely removing the use of the "number" ng-filter will cause AngularJS to simply convert the expression to a string according to my requirements.
所以
{{ number_expression }}
而不是
{{ number_expression | number : fractionSize}}
