Anyone see a better way of doing this

[ICool]

I have a list of possible exposure values, which I need to compare with the calculated value, and choose the closest one.

// This finds closest match
If 0<exposure<0.00025
Then  Output "Closest exposure value is 1/4000"
Else If 0.00025<exposure<0.0005
Then Output "Closest exposure value is 1/2000"
Else If 0.0005<exposure<0.001
Then Output ""Closest exposure value is 1/1000"
...

This is quite tedious as there are 20 values or so to compare with . Does someone see a better way of doing this ?

make an array of limit values and use the loop

also note that
If 0<exposure<0.00025
is not a C

Yep , it's just pseudocode I need to make for now

You could use log to calculate the table starting point in O(1) time.
