I have two columns with the names, units, and range as follows:

Column1: Start_post
Units: Ft
Min Range: 100+50.30
Max Range: 150+20.65

Column2: End_Post
Units: Ft
Min Range: 150+60.30
Max Range: 500+20.75

Is there a way to define this constraint whilst maintaining the format?

I have two columns that look like this:

Start_Post  End_Post
----------  --------
102+20.45   153+19.22 
120+21.25   220+25.30
...         ...

And I want to introduce a constraint to each column:

• Start_Pos
  Min Range: 100+50.30
  Max Range: 150+20.65
• End_Pos
  Min Range: 150+60.30
  Max Range: 500+20.75

All values are in feet and follow a special format. It's a construction convention and I am not an expert but to my knowledge, 1+00 would be 100 feet. Essentially, taking the above range of 100+50.30 to 150+20.65 would mean a distance of 4970 ft. What I did was just remove the plus sign and subtract the two numbers. Hope that made sense.
