Is there a method that can be used to get an Integer's representation in bits? For example when provided: 0 gives 0 4 gives 100 22 gives 10110

To convert a string to integer in Kotlin, use String. toInt() or Integer. parseInt() method. If the string can be converted to a valid integer, either of the methods returns int value.
Method 1: Use Integer.toBinaryString(a) where a is an Int. This method is from the Java platform and can be used in Kotlin. Find more about this method at https://docs.oracle.com/javase/7/docs/api/java/lang/Integer.html#toBinaryString(int)
Note: This method works for both positive and negative integers.
Method 2: Use a.toString(2) where a is an Int, 2 is the radix Note: This method only works for positive integers.

Starting with Kotlin 1.3 the binary representation of a signed integer can be obtained by reinterpreting it as an unsigned one and converting it to string base 2:
a.toUInt().toString(radix = 2) If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
