#P1517. 高精求小数幂

高精求小数幂

题目描述

Problems involving the computation of exact values of very large magnitude and precision are common. For example, the computation of the national debt is a taxing experience for many computer systems.

This problem requires that you write a program to compute the exact value of Rn where R is a real number ( 0.0 < R <= 9999.9) and n is an integer such that 0 < n <= 250.

输入格式

The input will consist of a set (less than 11) of pairs of values for R and n. The R value will occupy columns 1 through 6, and the n value will be in columns 8 and 9.

输出格式

The output will consist of one line for each line of input giving the exact value of R^n. Leading zeros should be suppressed in the output. Insignificant trailing zeros must not be printed. Don't print the decimal point if the result is an integer.

提示

If you don't know how to determine wheather encounted the end of input:

s is a string and n is an integer

C++ while(cin>>s>>n)

{ ... } c while(scanf("%s%d",s,&n)==2) //to see if the scanf read in as many items as you want

{ ... }
