The PHP ceil() function returns the next highest integer value by rounding up value of a floating poing number if necessary.

I couldn't find any functions to do what ceiling does while still leaving I specified number of decimal places, so I wrote a couple functions myself. round_up is like ceil but allows you to specify a number of decimal places. round_out does the same, but rounds away from zero. <?php // round_up: // rounds up a float to a specified number of decimal places // (basically acts like ceil() but allows for decimal places) function round_up ($value, $places=0) { if ($places < 0) { $places = 0; } $mult = pow(10, $places); return ceil($value * $mult) / $mult; } // round_out: // rounds a float away from zero to a specified number of decimal places function round_out ($value, $places=0) { if ($places < 0) { $places = 0; } $mult = pow(10, $places); return ($value >= 0 ?

The ceil() function returns the smallest integer that is greater than or equal to the number whose ceiling needs to be calculated.

May 21, 2021 - So we should use ceil(). Consider another situation where you have to determine how many people can be fully fed with the available food. In this case, you only have to invite people if you are certain they can be fed with the available food without ordering anything extra. We will have to ignore the leftover food which cannot feed an adult. So we should use floor(). The PHP round() function is different from floor() and ceil() because it takes us to the nearest integer (when no precision is specified) instead of always rounding up or down.

November 1, 2023 - The ceil function in PHP, available since PHP 4 and still available to use in the latest versions of PHP, including PHP 8+, allows you to round fractions up to the nearest highest integer value.

(PHP 3, PHP 4 )ceil -- Round fractions up · float ceil ( float value) Returns the next highest integer value by rounding up value if necessary. The return value of ceil() is still of type float as the value range of float is usually bigger than that of integer.

Both ceil() and floor() take just one parameter - the number to round. Ceil() takes the number and rounds it to the nearest integer above its current value, whereas floor() rounds it to the nearest integer below its current value. Here is an example: <?php $someval = 4.9; $ceiled = ceil($someval); ...

PHP ceil() function returns the smallest integer value that is bigger than or equal to given parameter.
