how to evaluate pi out to 28 decimal places.

I am using matlab on my school campus for a math project. I have tried every way i know how to express pi out to the 28 decimal place, but i can only get it to go to the 16th place than a bunch of zeros after that. Is there a specific code that i can put in that will let me go out that far or is that the farthest..

Answer 1

char(vpa(sym('pi'),28))

Note that this will be a string. You can't store 28 decimal places of Pi in an IEEE 754 double precision number.

thank you that is exactly what i needed... i dont know why it was so hard for me to find

[Juan]

is there anyway to write it so it does not round the last number off
