What's the reason to use return value in parenthesis?

[Guest]

I've seen a lot of times using return value in parentesises -
{
....
return (true);
}

What's the reason for this? Can smb explait it?

PS: they do return predefined values, not calculated like returd (I*(d/4))

There's no technical reason. In some cases it can increase readability,
but that's pretty rare IMO.

Michael,

I seem to remember very old C compilers (around 1974-75) that required these
parentheses, check for instance:

For me, there's no reason for using them today.

Hi,

no reason at all, probably it's auto generated code, I frankly doubt
somebody owuld do it like that manually

Basically, because it makes return look like a function. Note that in C
(and C++ and therefore C#), most constructs look like functions:
if(...)
while(...)
for(...)

One should note the in C/C++ there's no reason to wrap parens around the
operand of the sizeof operator -- still, most poeple do, because they think
of it as a function.
int l = sizeof long;
int i = sizeof(int);

This is noteworthy, because it C# cousin, typeof, *does* require parens,
even though there no more of a need for it then there is on sizeof or
return.
Type T = typeof(System.String);
