Hi everyone I need some help on doing this ranges between negative to positive numbers, I can handle this if it using a whole number but this is concern with decimal places..so I am noob with this..

For example :
Range from -0.99 to -0.9 with number counts from it. then
Range from -0.89 to -0.8 with number counts from it
Range from -0.79 to -0.7 with number counts from it and so fort..

and also I want to add all counts that within from the ranges above...
please see the attached file
DECIMAL COUNT RANGES.xlsx

THanks in Advance...
