What is the weather data covering the range of 359 to 360 degree I downloaded a grib file of oceanography (Mean Wave Period) from ERA-Interim and the longitude values give the value at the points is 0,1, 2, 3....357, 358, 359

If I have geographical coordinates that fall between the range 359 to 360 degree longitude. How can I represent them? 

Thank you for your time and concern reading my question, 

Sincerely,
Remember that 360° == 0°. They're the same line of longitude. So the gap between 359° and 0° is no more than the gap between 1° and 2°, and should be handled the same way.
