The ASCII character of 49 is 1. Alternatively, we can use String.format() method, string concatenation operator etc.. for all I know it could be matlab. Primitive data types Variables that store primitive data types store the actual data in memory where the variable is located. Syntax: str.charAt(index) Parameters On top of this, there are a couple of other ways as well. Each of the conversion functions converts its parameter to an equivalent representation within its datatype. Since int is higher data type (4 bytes) than char (2 bytes) so we need to explicitly typecast the int for the conversion. So, if you add 1 with 48, it becomes 49 which is equal to 1. Twitter handle: @arduinohack…, Digital Measuring Roller Using Microbit & Tinkercad, Pocket Dice! To convert higher data type into lower, we need to perform typecasting.
