We use different terms to describe different types of decimal numbers, for example: Integers are floating-point numbers without a fraction. They can either be positive or negative, e.g. 10, 400, or -5. 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.

We can convert these numbers back to decimal using the parseInt function. The parseInt function available in JavaScript has the following signature −. parseInt (string, radix); Where, the paramters are the following −. string −The value to parse.
