# Name of number representation

What do you call a number representation which constists only of integers, arithmetic operators and exponents/roots? I.e. no decimal numbers, trigonometric expressions, etc.

EDIT: To clarify, I want to represent e.g. the length of the hypotenuse of a 45-45-90 triangle with sides 1 as $\sqrt{2}$, not 1.414..., nor ${1}\over{\sin{\pi/4}}$. Similarly, I want to represent $\sin{\pi/12}$ as $\frac{\sqrt{6}-\sqrt{2}}{4}$, not 0.258...

I don't understand what you are asking. Can you elaborate? –  Eric Naslund Nov 25 '11 at 11:11
