Attributes

Remarks

Returns the smallest (closest to negative infinity) double value that is greater than or equal to the argument and is equal to a mathematical integer. Special cases: <ul><li>If the argument value is already equal to a mathematical integer, then the result is the same as the argument. <li>If the argument is NaN or an infinity or positive zero or negative zero, then the result is the same as the argument. <li>If the argument value is less than zero but greater than -1.0, then the result is negative zero.</ul> Note that the value of StrictMath.ceil(x) is exactly the value of -StrictMath.floor(-x).
