如何覆盖angularjs的默认值，以在负数周围使用括号（（））而不是减号（-）？

Question

Here is the $provided in the angular.js file that forces negative numbers to have the minus sign. I would rather not modify the angular.js source code.

$provide.value("$locale", {
  "DATETIME_FORMATS": {
*
*
*
"NUMBER_FORMATS": {
    "CURRENCY_SYM": "$",
    "DECIMAL_SEP": ".",
    "GROUP_SEP": ",",
    "PATTERNS": [
      {
        "gSize": 3,
        "lgSize": 3,
        "maxFrac": 3,
        "minFrac": 0,
        "minInt": 1,
        "negPre": "-",
        "negSuf": "",
        "posPre": "",
        "posSuf": ""
      },
      {
        "gSize": 3,
        "lgSize": 3,
        "maxFrac": 2,
        "minFrac": 2,
        "minInt": 1,
        "negPre": "-\u00a4",
        "negSuf": "",
        "posPre": "\u00a4",
        "posSuf": ""
      }
    ]
  },
*
*
*

I want to overwrite this behavior and have a custom configuration file that will give negative numbers parenthesis instead of the negative sign.

Current output: -48.25 Desired output: (48.25)

What about:

"PATTERNS": [
  {
    "gSize": 3,
    "lgSize": 3,
    "maxFrac": 3,
    "minFrac": 0,
    "minInt": 1,
    "negPre": "(",
    "negSuf": ")",
    "posPre": "",
    "posSuf": ""
  },
  {
    "gSize": 3,
    "lgSize": 3,
    "maxFrac": 2,
    "minFrac": 2,
    "minInt": 1,
    "negPre": "(\u00a4",
    "negSuf": ")",
    "posPre": "\u00a4",
    "posSuf": ""
  }
]

Try changing negPre and negSuf :

$provide.value("$locale", {
  "DATETIME_FORMATS": {
*
*
*
"NUMBER_FORMATS": {
    "CURRENCY_SYM": "$",
    "DECIMAL_SEP": ".",
    "GROUP_SEP": ",",
    "PATTERNS": [
      {
        "gSize": 3,
        "lgSize": 3,
        "maxFrac": 3,
        "minFrac": 0,
        "minInt": 1,
        "negPre": "(",
        "negSuf": ")",
        "posPre": "",
        "posSuf": ""
      },
      {
        "gSize": 3,
        "lgSize": 3,
        "maxFrac": 2,
        "minFrac": 2,
        "minInt": 1,
        "negPre": "(\u00a4",
        "negSuf": ")",
        "posPre": "\u00a4",
        "posSuf": ""
      }
    ]
  },
