@ExperimentalKotoolsTypesApi
@ExperimentalSince(version = KotoolsTypesVersion.V4_5_0)
fun create(number: Number): StrictlyNegativeInt

Creates a StrictlyNegativeInt from the specified number, which may involve rounding or truncation, or throws an IllegalArgumentException if the number is greater than or equals zero.


Calling from Kotlin

Here's an example of calling this method from Kotlin code:

val isSuccess: Boolean = try {
    StrictlyNegativeInt.create(-7)
    true
} catch (exception: IllegalArgumentException) {
    false
}
assertTrue(isSuccess)

The StrictlyNegativeInt type being an inline value class, this method is not available yet for Java users.

You can use the StrictlyNegativeInt.Companion.createOrNull method for returning null instead of throwing an exception in case of invalid number.
