Perhaps the EXACT() function is what you're looking for?

[a <-> b/c ] dual function key => exact( ), approx() example: poly1[1,(-3*a-3*b-7)/3,(7*a+7*b+2)/3,(-2*a-2*b)/3]; [a <-> b/c ] => approx(poly1[1,(-3*a-3*b-7)/3,(7*a+7*b+2)/3,(-2*a-2*b)/3]); => poly1[1.,(-3.*a-3.*b-7.)*0.333333333333,(7.*a+7.*b+2.)*0.333333333333,(-2.*a-2.*b)*0.333333333333] [a <-> b/c] => exact( Ans ); poly1[1,(-3*a-3*b-7)*1/3,(7*a+7*b+2)*1/3,(-2*a-2*b)*1/3]

Friend, Thank so much, exact() command is the function tha I need, But, [a b/c] works direct in all MATRIX elements and exact() doesnÂ´t work with matrix ... I wil try to do element by element...
Best regards!!

Friend, That was the trick BUT, ONCE running in the emulator program i GET "The application has crashed and will be restarted".... Would be nice if the calculator indicates the command that cause the failure and mainly the REASON (allowed types or hint ). Some idea ?
Best regards!! |
