minus

operator fun minus(other: NonPositiveInteger): NonNegativeInteger

Subtracts the other integer from this one.

Calling from Kotlin

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

val x: NonNegativeInteger = NonNegativeInteger.fromLong(42)
val y: NonPositiveInteger = NonPositiveInteger.fromLong(-8)

val result: NonNegativeInteger = x - y

val expected: NonNegativeInteger = NonNegativeInteger.fromLong(50)
check(result == expected)

Calling from Java

Here's an example of calling this function from Java code:

final NonNegativeInteger x = NonNegativeInteger.fromLong(42L);
final NonPositiveInteger y = NonPositiveInteger.fromLong(-8L);

final NonNegativeInteger result = x.minus(y);

final NonNegativeInteger expected = NonNegativeInteger.fromLong(50L);
final boolean check = result.equals(expected);
if (!check) throw new IllegalStateException("Check failed.");
