Re: Comparison of multiple-precision floating-point software

Thank you for the comparison!

The trig functions are unfortunately quadratic IIRC, and so they don't scale to high precision.

I would kill to have Arb's low-precision times for the non-basic functions, that's quite impressive. Hats off to Fredrik.

       Dear Pari developers,

I have updated my comparison of multiple-precision floating-point software:

Pari is within a factor of 2 of MPFR for basic arithmetic, except for the
square root, mul/sqr at 1000d, sqr/div at 10000d.

Your feedback is welcome.
