Hi,
the documentation of FPPREC:
,----
| - Variable: FPPREC
| default: [16] - Floating Point PRECision. Can be set to an
| integer representing the desired precision.
`----
seems to suggest that setting it to something higher than 16 would
result in a higher working precision than default double precision
numbers. However, while
,----
| block([fpprec: 2], print(ev(%pi, numer))) $
|
| 3.14
`----
...
,----
| block([fpprec: 14], print(ev(%pi, numer))) $
|
| 3.14159265358979
`----
,----
| block([fpprec: 15], print(ev(%pi, numer))) $
|
| 3.141592653589793
`----
all work more or less as expected, a higher fpprec does not print out
more digits as, e.g., N[Pi, 500] does in Mathematica or something like
N(Pi, 500); does in yacas.
Is there a simple way to get, say, the first 25 digits of pi in
Maxima?
Thanks in advance,
Albert.
