Re: Turning a sequence of expr into expr

[Bill Allombert <Bill.Allombert@math.u-bordeaux.fr>]

I made the computation on a 333MHz Ultrasparc II with 2Mb of cache

? ploth(t=100,110,[real(z=zeta(0.5+I*t)),imag(z)])
  ***   last result computed in 19,340 ms.
?  ploth(t=100, 110, if (1, z=zeta(0.5+I*t); [real(z),imag(z)]) )
  ***   last result computed in 19,360 ms.
? f(t)=local(z);z=zeta(0.5+I*t);[real(z),imag(z)]
? ploth(t=100,110,f(t))
  ***   last result computed in 19,400 ms.           

So Karim, if you want to resale your very slow machine , call me :-)

more seriously, with the just now CVS version I get

cd Osolaris-sparcv9; make gp

when I try to compile

The bug is that evalexpo is was? a macro ((0x00800000L)  + ( ulong x ))
and now it is a function but the macro has not been removed of parigen.h
there is another problem : evalexpoerr not declared
