Note that a radix is not required in parseFloat(), it will always return a decimal/base10 value. This function will round off the string to nearest integer value. It works without a radix but it is always a good idea to specify this because you never know how browsers may behave(for example, see comment Namir). For this you can use parseInt(string, radix). If I go by the title of your question, you need an integer. This should give you correct result even if your number is fractional like 1,700.55. Use regex inside replace() to get rid of each appearance of. From the variables in OP, it appears that there may be fractional numbers too, so, parseInt() may not work well in such cases(digits after decimal will be stripped off). Try using replace() to replace a, with nothing and then parseFloat() to get the number as float. He pointed out that parseFloat also does not take a radix so it is always in base10. A good example of this was written by below. I assumed you did as the title was convert to an integer. ParseFloat could also be used if you do not want rounding. Here is my favorite: 2 places: `num = parseInt(num * 100) / 100 `ģ places: `num = parseInt(num * 1000) / 1000 `įor more information on parseInt look at mdn. If you need decimal places there are a couple of tricks you can use. ParseInt always rounds to the nearest integer. If you are looking for a good tutorial here is one.A great tool to test regular expressions: Rubular and more info about them at mdn.'' replace the matched sections with an empty string, essentially deleting them. The global search will look for all matches (it would stop after the first match without this) More information on replace at mdn: `/` - start num = parseInt(num) ĭo this for each of your string numbers before adding them and everything should work. If you do not choose a radix it will default to 10 which was the correct value to use here. This will return a string with a number in it. You could remove the comma using a regex such as: var num = '1,700.00' Let’s see an example:įor (int i = 0 i < binarytoint.The reason parseInt is not working is because of the comma. We can also convert a binary string to an int in Java by using Math.pow() Method. Because a binary is a base-2 number system, the first parameter is the string, and the second argument is 2. The solution is parseInt (binary string, 2). Integer.parseInt() produces an int result that is computed using the radix number when we supply a string, The binary value in the example’s binaryInt object has to be changed into an int. Integer.parseInt(), the first method, converts the supplied string into an int. Int string=Integer.parseInt(binaryInt,2) The following is the parseInt() method’s example: Using the Integer.parseInt() function converts strings to integers. In Java, there are three solutions to convert a binary string to an int in Java, they are the following How to Convert Binary String to Int in Java?
