Description

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

This problem requires so 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 a integer such that 0 < n <= 25.

Input

The input would consist of a set of pairs of values for R and N. The R value would occupy columns 1 through 6, and the N value would be in columns 8 and 9.

Output

The output would consist of one line for each line of input giving the exact value of r^n. Leading zeros should is suppress Ed in the output. Insignificant trailing zeros must not being printed. Don ' t print the decimal point if the result was an integer.

Sample Input

95.123 120.4321 205.1234 156.7592  998.999 101.0100 12

High-precision multiplication ask the next FAI ICPC competition can be mixed in a variety of languages submitted here is to give the Java writing suggestions to master the large number of Java class

C + + version of yourself interested to knock it all off the decimal point minus the multiplication and then the decimal point is good.
