7-5 A divided by B (10 minutes)

Ha is really simple question - given absolute value is not more than two integers A and B 100, requiring you follow the "A / B = List" output format results.

Input format:
Input Given two integers A and B (-100≤A, B≤100) in the first row, separated by spaces between numbers.

Output format:
the output in the line: If the denominator is positive, the output "A / B = List"; if the denominator is negative, the denominator enclosed in braces output; If the denominator is zero, then the output should be commercially Error. Business output should retain two decimal places.

Input Sample 1:
-12
Output Sample 1:
-1 / 2 = -0.50
Input Sample 2:
1-3
Output Sample 2:
1 / (- 3) = - 0.33
Input Sample 3:
50
output sample. 3:
. 5/0 = Error
