Kotlin supports 3 types of integer literal
A signed integer literal can be assigned to a variable of any signed integer type. If no type is specified, Int (4 bytes) is assumed. If the value cannot fit into an Int, Long (8 bytes) is assumed.
These can be converted to long integer literals (signed 8 byte) by appending the suffix 'L' (lower case 'l' is not allowed as it is easily confused with the digit '1').▼
An unsigned integer literal is made by appending 'u' or 'U' to a signed integer literal. Unsigned literals can be assigned to any unsigned integer type, with UInt (4 bytes) being assumed if none is specified, or ULong (8 bytes) if the value cannot fit into a UInt.
