+ In Kotlin, a numeric value of one type is not automatically converted to another type even when the other type is larger.
+ This is different from how Java handles numeric conversions.
+
+ Here's a list of functions in Kotlin used for type conversion:
+
+ toByte()
+ toShort()
+ toInt()
+ toLong()
+ toFloat()
+ toDouble()
+ toChar()
+
+ Note: There is no conversion for Boolean types.

+ val string1: String = "54"
+
+ // convert String to Int
+ val number2: Int = string1.toInt()

+ // "54"+11 = 5411
+ println("number1 = ${string1+11}")
+
+ // 54 + 11 = 65
+ println("number2 = ${number2+11}")
+
+
+ // smaller types are NOT implicitly converted to bigger types.
+ // This means that we cannot assign a value of type Byte to an Int variable without an explicit conversion
+
+ /*
+ val b: Byte = 1 // OK, literals are checked statically
+ val i: Int = b // Type mismatch. */
