--description--

Given a distance in miles as a number, return the equivalent distance in kilometers.

• The input will always be a non-negative number.
• 1 mile equals 1.60934 kilometers.
• Round the result to two decimal places.
• Remove unnecessary trailing zeros from the rounded result.

--hints--

convertToKm(1) should return 1.61.

assert.equal(convertToKm(1), 1.61);

convertToKm(21) should return 33.8.

assert.equal(convertToKm(21), 33.8);

convertToKm(3.5) should return 5.63.

assert.equal(convertToKm(3.5), 5.63);

convertToKm(0) should return 0.

assert.equal(convertToKm(0), 0);

convertToKm(0.621371) should return 1.

assert.equal(convertToKm(0.621371), 1);
