PHP Bug Type: *General Issues
Bug description: Math calculation problem with 1.19 - 1
Description:
------------
There seems to be a problem with the numeric calculation:
if ( (1.19 - 1) == 0.19 ) {
echo "@@";
}
The expression "(1.19 - 1) == 0.19" does not evaluate to true.
My environments (problem exists on both platforms):
WinVista: PHP 5.25
Debian: 5.2.0-8+etch10
Reproduce code:
---------------
if ( (1.19 - 1) == 0.19 ) {
echo "@@";
}
Expected result:
----------------
output: @@
Actual result:
--------------
output: <nothing>
