IF funtion and or funtion returningen wrong result when using decimal numbers.
Exampel:

a1= 300 b1=303,6 c1=b1-a1 d1=3,6 e1=if(c1<=d1;"ok";"not ok")

this one returns "not ok" which is wrong result !!??

a1=300 b1=303,5 c1=b1-a1 d1=3,5 e1=if(c1<=d1;"ok";"not ok")

this one returns "ok" which is right result.

Be aware that c1 and d1 is equal in both exampels, only the decimal value
changes.

Have i found a MAJOR NUG in Excel or am i doing something wrong ?
I've also tried formatting the cells but i doesnt help in anyway.
