By default, Maple will display results as their exact value if no floats are used. If there are floats used within the calculations, Maple will display the results as approximate values. You can make use of this to display your results in the approximate format.
For example entering
Pi/6 will result in a fraction, but entering
Pi/6.0 will result in an approximation. This can allow you to have compact results in floating point form without the use of evalf.
Another way to set the format of output is to use a user profile. This will result in slightly different output where entering commands such as
1/2*Pi will evaluate to
0.5*Pi rather than
0.5*Pi as input will still result in
1.570796327 as output.
To use a user profile you've made save it to
C:\Program Files\Maple 2020\profiles
then in Maple go
Edit>User Profile select the profile you wish to use then click "Apply and Set as Default".
