fast-xml-parser неправильно анализирует ввод XML

Question

Почему этот тест не проходит с fastxmlparser

 import parser from 'fast-xml-parser'    
    test("fastxmlparser", () => {
            let parsed = parser.parse('<detail><name>john</name><value>116347579610481033</value></detail>')
            expect(parsed.detail.value).toBe('116347579610481033')
        })


Expected value to be:
          "116347579610481033"
        Received:
          116347579610481040

        Difference:

          Comparing two different types of values. Expected string but received number.
