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.

define_variable (foo, 0, float);
fpprec : 600;
for m:301 step 1 thru 310 do(foo: bfloat(sum(k^m/3^k,k,1,2100)),foo: foo-floor(foo),disp(m,foo));

See also bfloat and fpprintprec.
