11/27/2023 0 Comments Convert string to integer![]() ParseInt(4.7 * 1e22, 10) // Very large number becomes 4 This example is going to return 4 (for very large numbers): This example is going to -15 in each case: Now you will come across an example where each example is going to return NaN. You are going to come across such an example, in which every line is going to return 15 as output. You are going to see some examples using parseInt: If in a particular radix, you need to convert a number to a string literal then you need to use number.toString(radix). If it becomes impossible to convert the first character cannot be converted to a number, then also parseInt returnsNaN.If the value of radix is not coming under the inclusive range of, then the parseInt returns NaN.Otherwise, the value is assumed to be 10 (decimal) if the input string is starting with any other value.The radix value is assumed to be 16 and the rest part of the string is parsed as a hexadecimal number if the input string begins with a zero followed by lowercase and an uppercase number.Like if the value is zero then it is going to be NaN or Infinity and the undefined is corrected to NaN. If necessary then a value that is parsed as a radix argument can be corrected to a number. Numbers to integer values are truncated by the parseInt. Now while converting, if the parseInt() comes across such a character, this is not a numeral within the specified radix, then parseInt ignores it and all of its succeeding characters and ultimately returns the integer value which is parsed up to the point. Numerals greater than 9 are indicated by the English alphabet if the radix is above 10, like A through F is used for hexadecimal numbers (base 16). 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:
