Fpprec

-- Option variable: fpprec Default value: 16

fpprec is the number of significant digits for arithmetic on bigfloat numbers. fpprec does not affect computations on ordinary floating point numbers.

r(x, N) := x^(1/N);
n : 12;
l : 1/(2^n);
t(x, n) := taylor(r(x, n), x, 0, 10);
plot2d([r(x,n), t(x, n) ], [ x, l, 1]);
load("f90");
f90(t= t(x,2));
fpprec: 128;
bfloat(sqrt(%pi));

See also bfloat and fpprintprec.
