How to write a regex to capture a number surrounded by other characters?

export interface ValueParserResult {
  value: number, 
  error: string
}

interface subParseResult {
  result: (string | number) [], 
  error: string
}

class ValueParser {

  parse(eq: string, values: {[key: string] : number}, level?: number) : ValueParserResult {
    const result: ValueParserResult = { value: 0, error: "" }
  
    const numberRe: RegExp = /([^|\(||/|/\-|-|\*|\*\-|+|\^])+([0-9.]*)([$|(|)|/|/-|-|*|*-|+|])+/g;
          
    const eqParse = eq.split(" ").join('');
    eqParse.replace(numberRe, (matched) => {
      return " ," + matched;
    })
    
    console.log(eqParse)
    return result;

  }
}

const vp = new ValueParser();
const values = {a: 22, b:-10, c: 5}

const eq = "123/456*82*(a+b/c)"

vp.parse(eq, values)

This captures the entire eqParse string and puts a space comma in front of it. I want to put the comma space before each value and not capture the strings before and after.
