matlab - The function sqrt() without parentheses returns weird value -


i've accidentally typed following in octave:

sqrt 25

and got back:

ans =     7.0711   7.2801

with parentheses, sqrt(25) returns correct result. happening without parentheses? matlab share same behaviour or specific octave? don't have matlab cannot check.

octave interpreting length-2 char array, , converting these ascii representation (50 , 53), getting square root. can done in matlab using:

 sqrt(double('25'))

matlab produces error sqrt isn't defined char inputs when used without parentheses.
