[HP-PIRME] BUG Pretty Print, Solution: abs => |...|, ABS => ||...|| - CompSystems - 12-12-2013
Hi, in the new firmware version there is a new command abs() that is different ABS()
v1:=[1,-2,3];
v1 .^ 2; => [ 1^2, (-2)^2, 3^2 ] => [ 1, 4, 9 ] // Super OK, power element by element
dot( v1, v1 ); 1^2 + (-2)^2 + 3^2 => 14 // Super OK
abs( v1 ); => [ 1, 4, 9 ] // Super OK, absolute value of each element
ABS( v1 ); => SQROOT(14) // OK, now ABS() (CAPITAL) == NORM()
Ans ENTRY from history to the input line
=> abs( v1 ) [BUG] should be in uppercase not lowercase
IDEA: bug solution ABS(...) == ||..|| => double ||
why better not to create a new command (NORM)and thus avoid ambiguity ( abs with ABS, CAS version 1.1.0.27)
NORM( v1 ); => || v1 || (show history) => SQROOT(14) // Super OK CAS version 1.1.1 =)

It's not just abs() vs ABS(). There are many cases of two (slightly) different commands -- one of the form "command()" and the other of the form "COMMAND()". The best anyone can do at this moment is to wait for a much bigger firmware update that consolidates the command names into some sensible scheme.

sorry google translator
the problem reported is not on command (abs or ABS) the bug happens when an expression is carried from history to the input line, decodes bad
BUG steps
v1:=[1,-2,3];
abs( v1 ); => [ 1, 4, 9 ] // Super OK, absolute value of each element
ABS( v1 ); => SQROOT(14) // OK, now ABS() (CAPITAL) == NORM()
Ans ENTRY from history to the input line
=> abs( v1 ) [BUG] should be in uppercase not lowercase
I think the only solution that ABS should be displayed in double vertical bar history
purge(v1);
abs( v1 ); => |v1| // OK
ABS( v1 ); => ||v1|| // OK, no |v1|
