Convert a integer to binary
I am trying to convert a number to a binary value. The application I am dealing with has checkbox questions and multiple answers can be checked. The values in the field vary depending on the number of answers available.
Thus if there are 4 checkbox answers the values can range from 1 to 15
checkbox one value = 1
checkbox two value = 2
checkbox three value = 4
checkbox four value = 8
so if all boxes are checked, the value would be 15 in the database.
binary value of 15 would be 1111
if only one and three are checked, the value is 5 which would be 101
This would allow me to figure out the boxes that were checked for reporting.
We have some questions with 10+ check boxes (medical application)
Any ideas would be greatly appreciated (of a function you have developed)
If you have a maximum of 9 questions then add the following enclosed in * to your formula,
if you have more question you need to chnage the 9 value to the maximum number of questions
while x (not equal to symbols) 0 do
(binary:= totext(remainder(x,2),0) & binary;
x:= int(x/2));
********************************
binary:= replicatestring('0', 9 - length(binary));
********************************
binary
