ask about a function

for example...
Col. A Col. B
12.34 0.886
12.34 0.886
12.34 0.886
12.34 0.886
12.23 0.732
12.23 0.732
11.46 0.732
16.04 0.931
16.04 0.931
16.04 0.931
Conditions:
Set 1. 11.6 14.3 14.6 16.7 17.9 18.3 20.7
Set 2. 0.76 1.17 0.75 1.01 0.9 1.2 1.19

Substract Set 1 and column A ....then differences are

-0.74 1.96 2.26 4.36 5.56 5.96 8.36
-0.74 1.96 2.26 4.36 5.56 5.96 8.36
-0.74 1.96 2.26 4.36 5.56 5.96 8.36
-0.74 1.96 2.26 4.36 5.56 5.96 8.36
-0.63 2.07 2.37 4.47 5.67 6.07 8.47
-0.63 2.07 2.37 4.47 5.67 6.07 8.47
0.14 2.84 3.14 5.24 6.44 6.84 9.24
-4.44 -1.74 -1.44 0.66 1.86 2.26 4.66
-4.44 -1.74 -1.44 0.66 1.86 2.26 4.66
-4.44 -1.74 -1.44 0.66 1.86 2.26 4.66

Also, substract set 2 and column B...outcomes are as follow

-0.13 0.28 -0.14 0.12 0.01 0.31 0.30
-0.13 0.28 -0.14 0.12 0.01 0.31 0.30
-0.13 0.28 -0.14 0.12 0.01 0.31 0.30
-0.13 0.28 -0.14 0.12 0.01 0.31 0.30
0.03 0.44 0.02 0.28 0.17 0.47 0.46
0.03 0.44 0.02 0.28 0.17 0.47 0.46
0.03 0.44 0.02 0.28 0.17 0.47 0.46
-0.17 0.24 -0.18 0.08 -0.03 0.27 0.26
-0.17 0.24 -0.18 0.08 -0.03 0.27 0.26
-0.17 0.24 -0.18 0.08 -0.03 0.27 0.26


the negative value means values in column A or B could not meet this condition..while the positive one means they could meet it....

I am thinking to convert the differences (set 1 and col A||set 2 and col B) from negative and positive to 0 and 1 or false and true. something like a binary function...then multiply them....the results are containing 0 and 1 or false and true. only both 1 or both true could be selected for further uses...

I hope this time it is clear....

Thanks in advance
