Abstract(in English)	Nemerical methods wih guaranteed accuracy are the numerical methods such that results and their error estimation are calculated simultaneously. Most of the methods are based on interval arithmetic. The purpose of this report is to implement elementary function for it. On the four basic operations of arithmetic, we can implement interval arithmetic correctly by controling the direction rounding of result. But for elementary functions, we can't implement in the same way. We show the method of making interval and some attention for programing with flooting point numeber system conforming to IEEE/754.
