I just want to WARN you about:

>>> (int) (290.15 * 100);
=> 29014
>>> (int) round((290.15 * 100), 0);
=> 29015

There is always intval() - Not sure if this is what you were looking for...

example: -

$floatValue = 4.5;
echo intval($floatValue);    // Returns 4

It won't round off the value to an integer, but will strip out the decimal and trailing digits, and return the integer before the decimal.

Here is some documentation for this: - http://php.net/manual/en/function.intval.php

Use round, floor or ceil methods to round it to the closest integer, along with intval() which is limited.

What do you mean by converting?

  • casting*: (int) $float or intval($float)
  • truncating: floor($float) (down) or ceil($float) (up)
  • rounding: round($float) - has additional modes, see PHP_ROUND_HALF_... constants

*: casting has some chance, that float values cannot be represented in int (too big, or too small), f.ex. in your case.

PHP_INT_MAX: The largest integer supported in this build of PHP. Usually int(2147483647).

But, you could use the BCMath, or the GMP extensions for handling these large numbers. (Both are boundled, you only need to enable these extensions)

Use round()

$float_val = 4.5;

echo round($float_val);

You can also set param for precision and rounding mode, for more info

Update (According to your updated question):

$float_val = 1.0000124668092E+14;
printf('%.0f', $float_val / 1E+14); //Output Rounds Of To 1000012466809201
