combination of commands

 combination of commands

using the dollar sign ($) to end each command except the last one.

eigenvalues(E)$float(%),numer$rectform(%);

Typically, we use the semi-colon (;) to end a Maxima command. If you use the dollar sign ($), instead of the semi-colon (;), the command is executed, but no output is shown. In the previous line, thus, the 'eigenvalues’ and the 'float' commands are executed, but no output is shown until the last command 'rectform' is executed. This way, we skip all the detailed outputs of the first two commands.

One more simplification we can do is to reduce the number of digits shown in floating point. By default, up to 16 digits are shown in floating point results. You may want to reduce the number of digits to, say, 6, by using: Numeric > Set displayed Precision... Type a 6 in the resulting form.
