Problem B. Exponentiation
时间限制 500 ms
内存限制 32 MB
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 R
n where R is a real number ( 0.0 < R < 99.999 ) and n is an integer such that 0 < n <= 25.
输入数据
输出数据
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.
