Existing CAS commands --> Prime discussion

[compsystems]

Hello

If you write on the entry line a: = 15; a + = 1; [enter] is shown in the history view [a: = 15, increment(a, 1)] [15,16] where a+=1 is interpreted as increment (a, 1) but the entry line of this sentence is not interpreted.

increment(a, 1) [enter] increment(a, 1)? expected 17


A command that is not in the catalog does not imply that the command internally is not within the functions of the Xcas source code, they may not make it visible yet, like many that I have reported and have ignored.

For example

bool( 1 ); [enter] true
bool( 0 ); [enter] false
bool( -1 ); [enter] true
