Author #38968 [NEW]: bitwise operators
lamotkin at softhome dot net

2006-09-26, 6:57 pm

From: lamotkin at softhome dot net
Operating system: Win98
PHP version: Irrelevant
PHP Bug Type: Documentation problem
Bug description: bitwise operators

Description:
------------
I wonder why didn't the documentation maintainers
read user comments for the bitwise operation page,
and CLEARLY specify the '>>' operator performs
SIGNED shift?
Shall this '>>' logic be kept for the future,
and is it for all platforms?
There would be great to add two new core functions:
'shr($value, $bit_count)' and
'sar($value, $bit_count)'.
It's not that hard to implement!
