Prettier has suddenly started adding parentheses to mathematical expressions

[levz0r]

Hello,

Using extension v0.8.2.

After upgrading from 0.7.0, Prettier formatter has started adding parentheses to math expressions.

.unibeautifyrc.json:

{
  "JavaScript": {
    "beautifiers": ["Prettier"],
    "indent_style": "space",
    "indent_size": 2
  },
  "HTML": {
    "beautifiers": ["JS-Beautify"],
    "brace_style": "collapse",
    "indent_char": " ",
    "indent_scripts": "normal",
    "indent_size": 3,
    "max_preserve_newlines": 0,
    "preserve_newlines": true,
    "unformatted": ["sub", "sup", "b", "u", "h3"],
    "wrap_line_length": 125
  },
  "CSS": {
    "beautifiers": ["JS-Beautify"],
    "indent_char": " ",
    "indent_size": 4
  },
  "SCSS": {
    "beautifiers": ["Prettier"]
  },
  "TypeScript": {
    "beautifiers": ["Prettier"]
  },
  "JSON": {
    "beautifiers": ["Prettier"]
  }
}

Before upgrading:

function calculate_percents(fraction, number) {
  return number ? fraction * 100 / number : 0;
}

After:

function calculate_percents(fraction, number) {
  return number ? (fraction * 100) / number : 0;
}

package.json:

 "devDependencies": {
    "@unibeautify/beautifier-js-beautify": "^0.4.0",
    "@unibeautify/beautifier-prettier": "^0.9.0",
    "js-beautify": "^1.10.3",
    "prettier": "github:prettier/prettier",
    "unibeautify": "^0.17.0"
  }

I'd like to disable this functionality. Thank you.
