You, one of the best programmers in HDU, can get a very beautiful balloon if only you have solved the very very very... easy problem.

#### Input

Input contains multiple test cases. The first line of the input is a single integer T(0< T < 1000) which is the number of test cases. T test cases follow. Each test case contains a char C (+,-,*, /) and two integers A and B(0< A,B <10000).Of course, we all know that A and B are operands and C is an operator.

#### Output

For each case, print the operation result. The result should be rounded to 2 decimal places If and only if it is not an integer.
