Type a GP expression in the third (blue) box then hit <Shift>-<Enter> or click on the Evaluate button below it. A trailing semi-colon ; prevents output. You can assign to variables and define user functions. (Speed is approximately one fourth of native speed.)

Examples

?eulerphi (short help), ??factor (long help in new tab),
2*3, 10!, (1+x)^10, exp(Pi*sqrt(163)),
factor(2^128+1), factor(x^6+I),
intnum(x=-oo,oo,1/(1+x^2)), sumpos(n=1, n^(-3)),
sin(x), ellj(x + O(x^20)),
\p100: change default accuracy to 100 decimal digits
K=bnfinit(x^2+23); (huge: don't forget the ;), K.clgp
E=ellinit([0,1]*Mod(1,10^50+151)); ellcard(E),
polgalois(x^8-2), ellsearch(11) (loads packages on demand),
lfun(x^3-2, 2) (Dedekind zeta function from new Lfun package)

ecm(N, B = 1000!, nb = 100)=
