Is < faster than <=?

Question

Is if( a < 901 ) faster than if( a <= 900 ).

Not exactly as in this simple example, but there are slight performance changes on loop

Answer 1

Only if the people who created the computers are bad with boolean logic. Which they shouldn't be.

Every comparison (>= <= > <) can be done in the same speed.

What every comparison is, is just a subtraction (the difference) and seeing if it's positive/negative.
(If the msb is set, the number is negative)

How to check a >= b? Sub a-b >= 0 Check if a-b is positive.
How to check a <= b? Sub 0 <= b-a Check if b-a is positive.
How to check a < b? Sub a-b < 0 Check if a-b is negative.
How to check a > b? Sub 0 > b-a Check if b-a is negative.

Simply put, the computer can just do this underneath the hood for the given op:

a >= b == msb(a-b)==0
a <= b == msb(b-a)==0
a > b == msb(b-a)==1
a < b == msb(a-b)==1

and of course the computer wouldn't actually need to do the ==0 or ==1 either.
for the ==0 it could just invert the msb from the circuit.

Anyway, they most certainly wouldn't have made a >= b be calculated as a>b || a==b lol
