toByteOrNull
Parses the string to a Byte number or returns null if the string is not a valid representation of a Byte.
fun String.toByteOrNull(): Byte?(source)
fun main() {
val input1 = "100"
val byte1 = input1.toByteOrNull()
println("input1: $input1 -> $byte1") // output: input1: 100 -> 100
val input2 = "not a number"
val byte2 = input2.toByteOrNull()
println("input2: $input2 -> $byte2") // output: input2: not a number -> null
}
