Previous Comments: ------------------------------------------------------------------------ [2017-09-26 20:34:27] vasekdvor at gmail dot com Description: ------------ I find out that there is no documentation about Math function "round()" , about this situation: 'What will do the round function when there is invalid entry being passed to a "float $val" ?'. I think, that in others functions there is always written that if something goes wrong, that function will result in FALSE.For example floor function contains "This function returns FALSE in case of an error" in "Return values" section. I have a script where i am using round function and accidentally happened to me that i (by mistake) gives that function, an empty variable and after that function has proceeded, i saw that the returned result is 0. It's really confusing finding out what function creates this result if you have complex script. Expected result: ---------------- I think that there should be described what will the function returns if something goes wrong. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=75262&edit=1
