Write a program that mimics a calculator. The program should take as input:

Two floating-point numbers

The operation to be performed.

It should then output the numbers, the operator, and the result.

Additional notes:

Format your output to two decimal places.

For division, if the denominator is zero, output an appropriate message. The message should contain the word "error"

Some sample outputs follow:

3.5 + 4.0 = 7.50 13.973 * 5.65 = 78.95
