强制八度显示仅科学计数法

Question

See this code below, from Octave's Command Prompt:

>> log( 0.1 ) * 5e-8
 ans = -0.00000011513

As can be seen, there are quite a few zeros ( 6 to be exact). I would like if the number is displayed as 1.1513e-7. Or, scientific notation, by default. How does one do that?

Answer 1

You can change the format of the ouput displayed by octave with the function format ,

eg format short e forces short length exponential notation, which seems that is what you want.
