format short, format long, format short E, format long E, format rat

How can i represent a number let's say 1231312.1232323 with the formats long/short/long e /short e /rat more elegant or in a single code line without having to write 10 colums i was thinking of the fprintf and format spec commands . P.S i'm very much a beginner in matlab :) .

For a single value I would suggest the fprintf function:

v=1234567.1234567;
fprintf('%.7f\n',v)

1234567.1234567

so in conclusion what i'm hoping for is not possible ?

format short
a, b, c
format long
a,b,c
format short e
a,b,c
format long e
a,b,c
format rat
a,b,c

i did it like this ,was wondering if i could do it all in a single command line

I'n not sure why you would want that, but sure:

a=rand;b=rand;c=rand;
for f={'short','long','shortEng','longEng','rat'}
    format(f{1})
    a,b,c
end

Which you can put in a single line if you insist:

for f={'short','long','shortEng','longEng','rat'},format(f{1}),a,b,c,end

thx :) quote " I'n not sure why you would want that, but sure "

why not ? for diversity and cause it's fun learning new stuff and providing different answears /methods to the same question than the expected ones .

Maybe it is just that I prefer having full control by using fprintf or sprintf, and I don't see the benefit of spamming the command window with the same value in different formats.

But at least you have an example here of how you can convert one syntax for format to another, and how you can use any object array in a for loop, which will then be processed column by column.
