Question

--------------------------
Fruit                Trees
--------------------------
Apple                1098
Banana                500
Grapes                460
--------------------------
TOTAL                2058
--------------------------

Now, I want to find out, in form of percentage, how many trees are there for each fruit type. So, this is what I did

---------------------------------------------------------
 Apple              floor((1098*100)/2058)          53%
 Banana             floor(( 500*100)/2058)          24%
 Grapes             floor(( 460*100)/2058)          22%
---------------------------------------------------------
 TOTAL                                              99%

As you can see, 1% is lost in flooring values

I need logic in a way that whatever the values are for each fruit, total should get to 100%.
Above one is SAMPLE DATA, number of tree for each fruit, and number of fruits can increase or decrease.

Answer 1

Just use round() instead of floor()?

But always be careful with adding rounded numbers or percentages. Better use the original values to calculate the total.
