From the Docs:
$a << $b | Shift left | Shift the bits of $a $b steps to the left (each step means "multiply by two")
$a >> $b | Shift right | Shift the bits of $a $b steps to the right (each step means "divide by two")
What you want is one of these 🙂
$a < $b | Less than | True if $a is strictly less than $b.
$a > $b | Greater than | True if $a is strictly greater than $b.
$a <= $b | Less than or equal to | True if $a is less than or equal to $b.
$a >= $b | Greater than or equal to | True if $a is greater than or equal to $b.
