# Failing Tests

These tests fail and haven't been fixed yet as they would likely take major
refactoring to fix, which I may not have time to do before finals week.

## Integer i64 Overflow
code: `9223372036854775808:i64`  
error: `Integer overflow: value exceeds range for i64.`

This test fails because the parsed integer has already overflowed inside the
interpreter, so an integer token is returned with no overflow error detected.

## Integer i64 Underflow
code: `-9223372036854775809:i64`  
error: `Integer overflow: value exceeds range for i64.`

This test fails because the parsed integer has already overflowed inside the
interpreter, so an integer token is returned with no overflow error detected.

## Integer u64 Overflow
code: `18446744073709551616:u64`  
error: `Integer overflow: value exceeds range for u64.`

This test fails because the parsed integer has already overflowed inside the
interpreter, so an integer token is returned with no overflow error detected.

## Integer i16 Binary Sample
code: `0b1111111100000000:i16`  
value: `-256`

This test fails because the interpreter fails to recognize this as a negative
number, and parses is as `65280`, which is greater than the signed 16-bit max of
`32767`, resulting in an overflow error.

## Float Default No Leading Digit Negative
code: `-.25`  
value: `-0.25`

This test fails because the interpreter fails to recognize a token starting with
both a `-` then a `.` then a digit, as a numeric literal, resulting in it being
interpreted as an identifier.
