toStrictlyNegativeIntOrNull
@ExperimentalSinceKotoolsTypes(version = "4.3.1")
Returns this number as a StrictlyNegativeInt, which may involve rounding or truncation, or returns null
if this number is positive.
Here's some usage examples:
var result: StrictlyNegativeInt? = (-1).toStrictlyNegativeIntOrNull()
println(result) // -1
result = 0.toStrictlyNegativeIntOrNull()
println(result) // null
result = 1.toStrictlyNegativeIntOrNull()
println(result) // null

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