Astrological Chart Mathematical Calculator

I want to be able to enter a 3 digit number from 000 to 999 along with a decimal number from 0.01 up to 29.59.
These are used to find common numbers in this manner - enter the number then add or subtract its own square root. For example I enter 742 and 26.21 and it creates a list of common numbers of 169, 251, 333, 415, 850 & 932.
This is just a part of the build that utilize these common numbers to match up to an additional more complicated calculations.

Vision an astrological chart. On this chart is placed 3 digit numbers around the sphere going from 000 to 999 - I have them placed in a specific starting grid.

Now, on an astrological chart are numbers of degrees and minutes.

I need to enter specific degrees and minutes, making them a decimal number, along with the 3 digit whole numbers that are on the sphere with that corresponding decimal. For example 16.50 & 332, 692.
I will enter 10 of these entries in the same query.
Now, the decimals represent one of 360 spots on the sphere, and if you know anything about astrology the degrees and minutes go from O.00 to 29.59.
I need to enter those 10 decimals and the 3 digit whole numbers that same spot represents, it can be 2 or 3 numbers depending on the position, and utilizing the square root math again I need to add or subtract the decimals square root of itself to find if any of those numbers are in common with the results from the first calculations results.

In addition to this calculation additional calculations need to happen. I used 16.50 as an example, but when the query is submitted I need it to search one tenth plus and minus as well (a margin of error) so not only 16.50 but 16.49 and 16.51 as well.
Now, there will be a time when a decimal is used that falls at the edge of a degree change, lets say 16.59. When this occurs and we are using the error, this needs to be in the calculation whereas, 16.59 is also 16.58 and 17.00, the before and after tenth.

And one last item, when making a query I need to be able to select a before and after number of degrees of each of the 10 positions. For example if I enter 16.50 and 332, 692 and of course all the other 9 positions, I want to be able for the system to run query on a number of degrees before and after, like 2 positions before and after, 6 positions & 9 positions.
So 16.50 and I select 6 positions I want the program to compute the previous 6 and the 6 after 16.50, so 16.50, 15.50, 14.50, 13.50, 12.50, 11.50, 10,50 along with 17.50, 18.50,19.50, 20.50, 21.50, 22.50 and the system will know the corresponding whole numbers those represent, for example 15.50 would then be 333 and 693, then all computing of the decimals with the tenth before and after for each position, then the matching of them up with the first calculation results.
There will be times that when this before and after sequencing happens that there will be overlap of the decimals and the whole numbers they represent.


I know it sounds like a lot but its really very simple and I may be over explaining.

If you have the knack with the numbers and you have a grasp on how a 360 position sphere can look with all the numbers inserted then this may be for you.

I will worn you, I utilize windows seven on an old laptop so nothing fancy just a simple program that is user friendly, quick and most importantly ACCURATE.

NO EXCEL !! Just a simple behind the scenes operation with an easy front end screen to make entries and get results.

I will try my best to answer questions.

I know bids for jobs go quick on here but PLEASE before bidding make sure you have thought it through and are really capable of undertaking the gig and completing it.

Ive included a chart as an example.

Thanks
