Show answers in command prompt in decimal form

Hello I would like to make it so everything I "calculate" using the editor window will show up in the command window in decimal form.... Currently the command window likes to show it in fractional form like this.....

x0 =

(609*sin(3137475482873511/281474976710656 - 2*atan(11258999068426240/272960367009995457 - 74634127018254239162355017481176449^(1/2)/272960367009995457))*exp(-40/87))/(20000*sin(2*atan(11258999068426240/272960367009995457 - 74634127018254239162355017481176449^(1/2)/272960367009995457))) + 609/20000

v0 =

(1910722569069968199*cos(3137475482873511/281474976710656 - 2*atan(11258999068426240/272960367009995457 - 74634127018254239162355017481176449^(1/2)/272960367009995457))*exp(-40/87))/(22517998136852480000*sin(2*atan(11258999068426240/272960367009995457 - 74634127018254239162355017481176449^(1/2)/272960367009995457))) - (7*sin(3137475482873511/281474976710656 - 2*atan(11258999068426240/272960367009995457 - 74634127018254239162355017481176449^(1/2)/272960367009995457))*exp(-40/87))/(2000*sin(2*atan(11258999068426240/272960367009995457 - 74634127018254239162355017481176449^(1/2)/272960367009995457)))

I know that you can use commands like vpa or just simply copying and pasting the nomber back into the command prompt will yield an easier to read version, however I would like to set a setting that will alway no matter what will calculate it down to a decimal version, thanks in advance for any help!

Sorry, but no. You cannot simply set a flag that will automatically call vpa for you on every result.

As well, copying and pasting a result like that will convert it to a double, NOT a symbolic result. So you may well end up with a significant precision loss when you do so. Be careful, as if there is subtractive cancellation involved, the result as a double may be meaningless.

hmmmm I see thanks for posting, I find it so unbelievably wierd that matlab would not have a settings tab to atleast visually show answers in the command window as decimals, because its a great visual aid f0r stupid people who can not calculate big nombers with fractions in their minds, This would really help with my debugging of my mistakes, welp I guess ill just take out my casio calculator every time and punch the nombers in to calculate calculate them down to a decimal haha xD (btw im joking no way in hell am i doing that for any fractional nomber that has around....... 100 nombers and 10 minuses and pluses)

Is there any command line i can put in the editor??? they have a command line to "close all/clear all"

[Walter Roberson]

"close all" in any program is typically a mistake, and "clear all" in a program is always a mistake.

There is no setting for automatically using vpa. You can use the vpa() command at need.
