# Base changing for transcendental numbers

 P: 14 Hi All, This might be a silly question but can anyone tell me with certainty if it is possible to convert a transcendental number into a terminating decimal by base changing? If that is possible that is insanely awesome.  Sorry that was completely not what I was wondering. I meant this: Does an integer based number system exist, wherein some transcendental number when converted into this number system is a finite number. I think I worded it ok that time.
 Sci Advisor P: 834 First, decimal means base 10. You can't take a transcendental number written in base 10, and change to base 10, and expect the expression to be different. (This is not correct for all real numbers. But you only asked for transcendental.) If you are asking "given a transcendental number x, does there exist a base, so that x can be written finitely in that base?" Then the answer is yes: base x. For example the golden ratio is "10" in base phinary. Edit: I just realized that phi is not transcendental. But the idea is the same.
 Math Emeritus Sci Advisor Thanks PF Gold P: 39,569 In other words, given any transcendental number, x, we can write x in the number system having base x, as "10".
 P: 14 Base changing for transcendental numbers Hi Folks & thanks for responding. I think I should have been more explicit in my question though. I'm gonna go back and change it. I meant for the base to be an integer. As far as me calling it a decimal... yeah that was pretty stupid.
 P: 2,466 like how $2^{\aleph_0}=10^{\aleph_0}$ which equals $\aleph_1$ is that what you mean. edit: I confused transcedental with transfinite. but I still think you could change the base.
