Google Weather API temperature conversion

Google weather API shows temperature in Fahrenheit.

After watching this post, I was able to convert temperature from F to C.

However, it shows like 17.222222222222° C - 28.888888888889° C, Clear. How can i make it only 17° C-28° C.

Thanks in advance.

function toCelsius($deg)
{
  return floor(($deg-32)/1.8);
}

You can use floor to return the next lowest integer value by rounding down value if necessary.
