toStrictlyNegativeIntOrThrow
@ExperimentalSinceKotoolsTypes(version = "4.4")
Returns this number as a StrictlyNegativeInt, which may involve rounding or truncation, or throws an IllegalArgumentException if this number is positive.
Here's some usage examples:
val result: StrictlyNegativeInt = (-1).toStrictlyNegativeIntOrThrow()
println(result) // 1
0.toStrictlyNegativeIntOrThrow() // IllegalArgumentException
1.toStrictlyNegativeIntOrThrow() // IllegalArgumentException

You can use the toStrictlyNegativeIntOrNull function for returning null
instead of throwing an IllegalArgumentException when this number is positive.
