Rounds the number.. Converts it into a string.. Returns the number as a string.. How many decimal places can a float hold?The float data type has only 6-7 decimal digits of precision. That means the total number of digits, not the number to the right of the decimal point. How do I restrict a float value to only two places after the decimal point in JavaScript?To limit the number of digits up to 2 places after the decimal, the toFixed() method is used. The toFixed() method rounds up the floating-point number up to 2 places after the decimal.

In this post, I'll present two different strategies to overcome these precision issues: one for decimal numbers and another for integer numbers. |
