Implement the `String.fromCodePoint(_)` primitive that creates a string from a Unicode code point, with validation for integer range 0–0x10ffff. Extract inline UTF-8 encoding logic from `readUnicodeEscape` in the compiler into new `wrenUtf8NumBytes` and `wrenUtf8Encode` utility functions in `wren_utils`, and add `wrenStringFromCodePoint` helper in `wren_value`. Update documentation for core classes to add "Methods" and "Static Methods" section headers, and include `String.fromCodePoint` docs with example. Add a test file `from_code_point.wren` covering various code points.
Adds a new `atan(_)` primitive method to the Num class that wraps the C
`atan2` function, allowing callers to compute the arc tangent of the
number divided by a given argument `x` while using the signs of both
numbers to determine the correct quadrant of the result. The
implementation registers the primitive `num_atan2` in the core VM
initialization and documents the new method in the core library
reference.
Add the missing `tan` method to the Num class, implementing the tangent
trigonometric function. This fills the gap between the existing `sin` and
`cos` methods, providing a complete set of basic trigonometric operations.
- Register `num_tan` primitive in the VM core initialization
- Implement `DEF_PRIMITIVE(num_tan)` using C's `tan()` math function
- Add documentation entry for `tan` in the core library reference
Implements a new `fromString` static method on the `Num` class that attempts to parse a string as a decimal number literal using `strtod`. Returns the parsed `Num` value on success, or `null` if the string does not represent a valid number. Includes runtime validation that the argument is a string, and adds test coverage for positive, negative, zero, and decimal inputs as well as non-numeric strings.
