And based on the radix value, if the radix value is 8, then it converts from octal, if the radix value is 16 then it converts from hexadecimal, a radix of 10 converts from the decimal, and so on. The return value is going to be an integer, if the return value is not Nan, and the return value is based on the first argument passed. First, the argument is converted to a string.Now, go through the description for this parseInt(): The first character which is non-whitespace is not going to convert to a number.

The modulo 2**32 of the radix is greater than 36 and smaller than 2.When a string is given as an argument to the parseInt, an integer is parsed.īut in certain cases, it can also be NaN, just like: Now you will look into the return values: It will be corrected to a number if the radix value is not a number type. So this is how the radix of the string is represented. The radix is represented by a range of integers from 2 to 36. Radix is the base of the mathematical numeral system. The second parameter is an optional parameter which is radix: If in this argument, a white space is leading, then it is ignored. If the argument which has been passed is not a string, then it is converted to a string using an operation which is called toString. So the first parameter is String, this is the value that is to be parsed. Now, explore the parameters which should be passed to this function:
