Exclusive Easy 1 Basics Microsoft

Implement a calculator that supports four basic operations:

add(a, b)      // Returns a + b
subtract(a, b) // Returns a - b
multiply(a, b) // Returns a * b
divide(a, b)   // Returns a / b (floating-point division, not integer division)

Important: All functions must handle both integers and floating-point numbers. If the result is a whole number, output it as an integer (e.g., 4 not 4.0). Otherwise, output the decimal value (e.g., 2.5).

Floating-point precision: Due to binary representation limitations, some decimal numbers cannot be stored exactly (e.g., 0.1, 5.1). When the mathematical result should be a clean decimal but floating-point arithmetic introduces small errors (e.g., 1.0999999999999996 instead of 1.1), round to a reasonable precision (10-12 decimal places) before outputting. If the rounded result is a whole number, output it as an integer.

Input Format

First line: integer Q (number of queries)
Next Q lines: a [operator] b where a and b are numbers and [operator] is +, -, *, or /

Output Format

Output Q numbers, one per line, representing the result of each query. Omit .0 from whole number results.

Constraints

$-10^9 \leq a, b \leq 10^9$
$1 \leq Q \leq 10^5$
The result will fit in a 32-bit signed integer
All inputs will fit within 5 digits of precision.
