Description
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 < 99.999 ) and n is an integer such that 0 < n <= 25.
Input
The input will consist of a set 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.
Output
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.

0.4321 20
5.1234 15
6.7592 9

題目翻譯：
對數值很大、精度很高的數進行高精度計算是一類十分常見的問題。比如，對國債進行計算就是屬於這類問題。
現在要你解決的問題是：對一個實數R(0.0 < R < 99.999)，要求寫出程序精確計算R的n次方(Rn)，其中n是整數並且0 < n <= 25。
【輸入格式】
輸入包括多組R和n。R的值佔第1到第6列，n的值佔第8和第9列。
【輸出格式】
對於每組輸入，要求輸出一行，該行包含精確的R的n次方。輸出需要去掉前導的0和後面不要的0。如果輸出是整數，不要輸出小數點。
分析：
這道題就是一個高精度的低精度冪的問題
