  • To validate decimal numbers in JavaScript, use the match() method. It retrieves the matches when matching a string against a regular expression. It retrieves the matches when matching a string against a regular expression.
  • In JavaScript all numbers are IEEE 754 floating point numbers. Due to the binary nature of their encoding, some decimal numbers cannot be represented with perfect accuracy. This is analagous to how the fraction 1/3 cannot be accurately represented with a decimal number with a finite number of digits. Once you hit the limit of your storage you'll need to round the last digit up or down.
  • Likewise, when you are adding and subtracting decimals, you first need to line up the place values of the numbers so the decimal point doesn't end up in the wrong place.
  • Since floating point math is inherently imprecise, try using toFixed() to round it to a suitable number of digits: var cena_dodana = (cena_poczatkowa + 1.01).toFixed(4);
