Is there any way to print at least 20 significant figures in Octave?

I need to print the result of a program with 20 significant figures, but I don't know how to print more than 15开发者_高级运维 figures (format long). Is there any way to achieve this?


You can control the format of your output with printf, just like in C, by following this syntax with these format specifiers:

> printf('%.20f\n', pi)
