Subject: [PATCH] Increase the tolerance of approx acos and cbrt tests

On engines which pass through these functions to the libc library they can
return slightly different values depending on the OS and archictures.

Showing a few example with Python, which also passes these through to libc on a
few platforms I have access to:

Ubuntu Noble, Python 12, s390x
```
>>> import math

>>> math.cbrt(math.e)
1.3956124250860897

>>> math.acosh(math.cosh(0.2))
0.20000000000000023
```

Ubuntu Noble, Python 12, x86_64
```
>>> import math

>>> math.cbrt(math.e)
1.39561242508609

>>> math.acosh(math.cosh(0.2))
0.20000000000000023
```

MacOS 14, Python 12, x86_64
```
>>> import math

>>> math.cbrt(math.e)
1.3956124250860895

>>> math.acosh(math.cosh(0.2))
0.20000000000000026
```
