[Cfp-interest 1918] Re: Errata for IEEE 754-2019

[Paul Zimmermann]

       Hi Mike,

I wonder about the entry "Should more special values be added [in 9.2.1]?".
This is not really an erratum, isn't it? The two given examples of acospi(0)
and acospi(-1) follow both from the definition of acospi(x)=acos(x)/pi.
