When two variables are declared as either single or double and used for
comparison, pls see below

Note that try1 and try2 are getting the value from excel worksheet, in this
case, may be
both are 508.19

double try1
double try2

when the following statement is executed, the excel micro will issue an
error try1 not equal to try2 even if both have the values of 508.19

if try1 < try2
generate eror message ' try1 not equal to try2'
end-if

Does anybody know why?
