This is derived from tests/general/float_test and appears to be the reason for the failure of that
test with non-C backends.

The strings above should be "16" and "10" respectively.

At least part of the bug can be attributed to commit b1af59cb29ac31db9fc5b3422fced505facabad1
where the replacement of string.substring was replaced by string.between incorrectly.

Yes, that commit introduced an off-by-one error at string.m:4038. Fixing that fixes the problem.
I'll commit a fix after I run some further tests to see if anything else is broken.
