Object Pascal - Parenthesis operator: ( )

We can use parentheses to change the order of expression evaluation, in other words, we can override operator precedence.

( )

( expression )

Parenthesis operator the possible of use:

x := 90 mod 8;    // x = 2
y := 15 mod 4;    // y = 3
z := (x mod y) mod 5;// z = 2

Even one example in what situations we can use the operation parenthesis operator:

i * $FF
10 * 3.14
(10 - j * 0.5) * 2

Other pieces of example codes:

(x shr 2) shr 2

(i and j) < 128

double((x * y))

(x shl y) shl 2

(j + 10) <= 128

(b or c) or a
