Description:
------------
when you round(378240328403284.234) or other large numbers... php automatically translates it with scientific notation... i'm just wondering if we can add that as an option only... say round(#,#,SCIENTIFIC) or whatnot...

i know you can use number_format()... but that's not the intended use of that function.

Reproduce code:
---------------
<?
echo round(324324434324322324.324,2);
?>

Expected result:
----------------
outputs "324324434324322324.32"

Actual result:
--------------
outputs "3.2432443432432E+17"

round() doesn't change the number, output depends on the value of "precision" in your php.ini.

can we change that? these things should be able to be changed on the fly... no?
in my mind... round() should do just that... rounding the number... not be translating with scientific notation... i can see if we make that an option to the round()... some may find that useful... but for the rest of us... having super large numbers being translated on the fly into scientific notation, is just a recipe for disaster...

Use (s)printf() if you want to format the numbers yourself.

What kind of disaster are you talking about?

say... in a budgeting program(if only i had that much money LOL)... where your expecting numbers to firstly round into nice dollar amounts, then to add up all nice and pretty... well... scientific notation doesnt add up all that nicely...

i know theres work arounds... my complaint isnt that i cant work around it... but that its not working, as it should be... round() should not be translating naturally...
