RE: Existing CAS commands --> Prime discussion
(11-29-2018 05:18 PM)ijabbott Wrote: Looking at the Giac/Xcas source code for exact and float2rational, they follow different code paths, but do similar things. The main functional difference seems to be that exact imposes a minimum epsilon value of 1e-14, whereas float2rational imposes a minimum epsilon value of 1e-11. Prime's exact() function can be controlled by setting epsilon to any value between 1e-6 and 1e-15. Since the output of float2rational() can therefore be obtained by exact(), there is no need to add float2rational to the Prime's vocabulary... especially now that QPI is also available: qpi(.324532453245) --> 295/909 <0|ΙΈ|0> -Joe- |
