Tests:

  • Add using Decimal.js

     
    for (var i = 0; i < 1000; i++) {
      Decimal('0.00253452345').plus(Decimal('0.042234'))
    }

  • Add using native numbers

     
    for (var i = 0; i < 1000; i++) {
      0.00253452345 + 0.042234
    }

  • Add using numerical strings parsed with Number

     
    for (var i = 0; i < 1000; i++) {
      Number("0.00253452345") + Number("0.042234")
    }

  • Add using numerical strings parsed with parseFloat

     
    for (var i = 0; i < 1000; i++) {
      parseFloat("0.00253452345") + parseFloat("0.042234")
    }
