Implement the `round` method on the Num class that rounds a number to the nearest integer using standard rounding rules (away from zero for .5). The implementation adds a new `num_round` primitive function in the VM core, registers it as a method on the Num class, includes documentation in the core module reference, and adds a comprehensive test file covering positive, negative, zero, and fractional cases.
This contains the automated validation suite for the VM and built-in libraries.
-
benchmark/- Performance tests. These aren't strictly pass/fail, but let us compare performance both against other languages and against previous builds of Wren itself. -
core/- Tests for the built in core library, mainly methods on the core classes. If a bug is inwren_core.corwren_value.c, it will most likely break one of these tests. -
language/- Tests of the language itself, its grammar and runtime semantics. If a bug is inwren_compiler.corwren_vm.c, it will most likely break one of these tests. This includes tests for the syntax for the literal forms of the core classes. -
limit/- Tests for various hardcoded limits. The language doesn't officially specify these limits, but the Wren implementation has them. These tests ensure that limit behavior is well-defined and tested.
