# Convert string to binary number javascript

The parseInt function parses a string argument and returns an integer of the specified radix the base in mathematical numeral systems. The source for this interactive example is stored in a GitHub repository. If you'd like to contribute to the interactive examples project, please clone https: An integer number parsed from **convert string to binary number javascript** given string. If the first character cannot be converted to a number, NaN is returned. The parseInt function converts its first argument to a string, parses it, and returns an integer or NaN.

If not NaNthe returned value will be the convert string to binary number javascript that is the first argument taken as a number in the specified radix base. For example, a radix of 10 indicates to convert from a decimal number, 8 octal, 16 hexadecimal, and so on. For radices above 10the letters of the convert string to binary number javascript indicate numerals greater than 9. For example, for hexadecimal numbers base 16A through F are convert string to binary number javascript.

If parseInt encounters a character that is not a numeral in the specified radix, it ignores it and all succeeding characters and returns the integer value parsed up to that point. Leading and trailing spaces are allowed.

Because some numbers include the e character in their string representation e. If radix is undefined or 0 or absentJavaScript assumes the following:. If the first character cannot be converted to a number, parseInt returns NaN. For arithmetic purposes, the NaN value is not a number in any radix. If NaN is passed on to arithmetic operations, the operation results will also be NaN.

To convert number to its string literal in a particular radix use intValue. The following may have an octal result, or it may have a decimal result. Always specify a radix to avoid this unreliable behavior.

The ECMAScript 5 specification of the function parseInt no longer allows implementations to treat Strings beginning with a 0 character as octal values. The parseInt function produces an integer value dictated by interpretation of the contents of the string argument according to the specified radix. Leading white space in string is ignored.

If radix is undefined or 0it is assumed to be 10 except when the number begins with the character pairs 0x or 0Xin which case a radix of 16 is assumed. Many implementations have not adopted this behavior as ofand because older browsers must be supported, always specify a radix. Get the latest and greatest from MDN delivered straight to your inbox.
