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),
  • ploth(x=1,100,[sqrt(2/(Pi*x)),besselj(0,x),-sqrt(2/(Pi*x))]),
  • 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)
  • E=ellinit("11a1");L=lfuninit(E,[0,100]); ploth(x=0,100,lfunhardy(L,x))
  • ecm(N, B = 1000!, nb = 100)=
    {
      for(a = 1, nb,
        iferr(ellmul(ellinit([a,1], N), [0,1], B),
          E, return(gcd(lift(component(E,2)),N))))
    }
    ecm(2^101-1)
