I have a floating point raster with values from 60 up to 95 (with decimals), it has 7077 pixels of 250x250m size.

Is there a way to sum all pixel values of this raster? For example, if the raster had 3 pixels with values of 60.20, 71.43 and 86.59, the sum would be 218.22.

I tried with zonal statistics and cell statistics, but it does not work. I am using ArcMap 10.1.
