#696 closed bug (fixed)

new greetings from exponent overflow hell

Reported by: kroeker@… Owned by: somebody
Priority: minor Milestone: 4-1-0 and higher
Component: dontKnow Version: 4-0-1
Keywords: overflow map Cc:


some overflow bugs as in seems fixed now.(which commit?)

Here is one more:

ring rng = 0,(x,y),dp;
short = 0;
poly h = x^2147483647;
ideal I = h;
ring G = 0,(a,b),dp;
short = 0;
ideal phi = a,b;
map m = rng,a^3,b;
m(I); // =a^2147483645*b , wrong!!

so it is not the end of the story. Also the computation takes about a minute to finish.
