Niagara and sqrt

I got a bad surprise when running some code on a T-1000 .

The code called sqrt rarly, but even then it turns out that my code uses

a huge fraction in trap handling.

Investigating I found that my T-1000 used 25000 cycles to calculate a sqrt.

I have a few questions:

Where were we told that niagara did not have sqrt implemented in hardware?

My googles search only found mentioning of that fact from linux port people.

And even if it is not implemented in hardware, why would it use 25000 cycles to compute it? I
