StrCmp Problem
Keywords: StrCmp StriCmp Compare strings numbers integers
Question:
I am using strCmp and the results are strange.
test=StrCmp("20","3")
Message("",test)
Shouldn't this return a 1 since string1 is greater than string2? But it always returns a -1. Why is this simple code returning thees results?
Answer:
You are confusing string comparison with numeric comparison. The StrCmp function compares characters in a string until it finds a difference. It then reports the relational position of the two differing characters relative to each other in the collating sequence. In this case it finds a difference at the first character and reports the relational difference between the character '2' and character '3' in the collating sequence. Since '2' is less than '3' in the collating sequence it is correctly returning -1.If you want to compare numbers I recommend using the relational operators instead.
num1 = 20
num2 = 3
If num1 == num2
Pause("","Num1 is Equal to Num2")
EndIf
If num1 < num2
Pause("","Num1 is Less Than Num2")
EndIf
If num1 > num2
Pause("","Num1 is Greater Than Num2")
EndIf
