Replying to [comment:25 pbruin]:
> Are the PARI developers aware of this precision issue?
No idea. I might report it.
> does PARI not strive for proven error bounds for functions such as
`eint1()`?
I don't think PARI does. However, the errors are quite large (over 30 bits
can be wrong), so perhaps that's a bug indeed.
