Decimal places in JavaScript

JavaScript has only one numeric type, so it's the one it should use. Of course, it has a maximum and it's the maximum you can use.

It's good to know that JS uses a numeric type based on binary floating point and this means that there will be no numerical accuracy if you need this does not, but by the above does not seem to be the case. The maximum is Number.MAX_VALUE .

console.log(Number.MAX_VALUE);

If this does not resolve, you will have to make or take a library that creates a type that meets your need.

The numbers in JavaScript are always of type Number , and always are 64-bit floating point in the IEEE 754 standard:

• Mantissa / Fraction: 52 bits;
• Exponent: 11 bits;
• Signal: 1 bit;

  

The maximum value that can be reached is approximately 3.4028235 × 10e38
