Nevertheless it is expected behaviour.
Argument type of these functions is string.
This is a bug report about an unexpected result not a feature request to
implement some magic non-locale-aware string cast.
Sorry :)

@mike PHP's shitty float to string cast shouldn't impede the workings of
bcmath. We've had this problem in the past several times (with stuff like JSON
etc) and the solution is to use some custom printf modifier for this.

This is actually expected behaviour because bcmath operates on strings and PHP
casts numbers to strings according to locale.

Description:
------------
Unexpected result on bccomp when using any decimal comma locale.
If an operand is a fraction, and the other is zero, the result seems to be
wrong.
Test script:
---------------
<?php
print setlocale(LC_ALL, "C")."\n";
print 1.1."\n";
print bccomp(1.1, 0)."\n";
//changing locale to a country which uses decimal comma
print setlocale(LC_ALL, "en_DK.UTF-8")."\n";
print 1.1."\n";
print bccomp(1.1, 0)."\n";
print setlocale(LC_ALL, "pt_BR.UTF-8")."\n";
print 1.1."\n";
print bccomp(1.1, 0)."\n";
?>
Expected result:
----------------
C
1.1
1
en_DK.UTF-8
1,1
1
pt_BR.UTF-8
1,1
1
Actual result:
--------------
C
1.1
1
en_DK.UTF-8
1,1
0
pt_BR.UTF-8
1,1
0
