Provide a general summary of the issue here

In 'de' locale the decimal separator is , , so theoretically a string like '1234.7' is invalid number, so i'd expect NaN as a result but we get 1234.7

const parser = new NumberParser('de', { useGrouping: false })
console.log(parser.parse('1234.7')) // 1234.7

In 'en' it works as expected and gives back NaN if a wrong separator is used

const parser = new NumberParser('en', { useGrouping: false })
console.log(parser.parse('1234,7')) // NaN

🤔 Expected Behavior?

const parser = new NumberParser('de', { useGrouping: false })
console.log(parser.parse('1234.7')) // NaN

😯 Current Behavior

const parser = new NumberParser('de', { useGrouping: false })
console.log(parser.parse('1234.7')) // 1234.7
