What is there utility of '=' sign in relational operators?

Question

for example: 7>4 is true and 7>=4 is also true.. so what role is the equal to sign playing ?

Answer 1

7> 7 is false but 7>=7 is true.
got the difference?

Answer 2

Just as 'standalone' expressions with literal values, there is no difference.

But when you need for example a condition to exit a loop, you will see, what the '>=' means.

Some pseudo-code to explain:

var = 1
Do
[... some code ...]
var = var + 1
Loop until var > 4

Changing the last line to:

Loop until var >= 4

will make the difference ... ;-)

Answer 3

1 > 1 - is 1 greater than 1? false
1 >= 1 - is one greater OR EQUAL to 1? true
the statement with the equal sign means INCLUDING the number
