Subject: [PHP-DEV] [DISCUSSION] bcmath: adding bcgetopts() and bcsetopts() to get or set bcmath options

Hello all,

Would adding a bcgetopts(): int and a bcsetopts(int $opts): void calls 
be useful?

At this time there's no way to influence bcmath's behavior other than 
bcscale().

An example of option that could be configurable through this mechanism 
would be automatic removal of trailing / leading zeros in the results 
returned by bcmath.

bcscale(10);
echo bcadd('1', '2');
result: 3.0000000

  If we could tell bcmath to strip the trailing zeros by calling

bcsetopts(bcgetopts() | BC_STRIP_TRAILING_ZEROS));


, the result should be just '3'.



Some options I could think of:
BC_STRIP_TRAILING_ZEROS
BC_STRIP_LEADING_ZEROS
BC_STRIP_ZERO_INTEGER (so instead of returning 0.5, it would just return .5)


The actual code to strip the trailing/leading zeros seems to already be 
in the library, just not exposed to the API (bc_rm_*() in 
libbcmath/src/rmzero.c).

I'm using PHP's bcmath extensively in a performance-sensitive 
application and sanitizing the results in PHP is a performance sink that 
could be avoided this way.

Thank you for your attention.
