ATAN2( float $xCoordinate = NULL, float $yCoordinate = NULL )
ATAN2
This function calculates the arc tangent of the two variables x and y. It is similar to calculating the arc tangent of y ÷ x, except that the signs of both arguments are used to determine the quadrant of the result.
The arctangent is the angle from the x-axis to a line containing the origin (0, 0) and a point with coordinates (xCoordinate, yCoordinate). The angle is given in radians between -pi and pi, excluding -pi.
Note that the Excel ATAN2() function accepts its arguments in the reverse order to the standard PHP atan2() function, so we need to reverse them here before calling the PHP atan() function.
Excel Function: ATAN2(xCoordinate,yCoordinate)
Parameters
- $xCoordinate
- The x-coordinate of the point.
- $yCoordinate
- The y-coordinate of the point.
Returns
float
The inverse tangent of the specified x- and y-coordinates.

CEILING( float $number, float $significance = NULL )
CEILING
Returns number rounded up, away from zero, to the nearest multiple of significance. For example, if you want to avoid using pennies in your prices and your product is priced at $4.42, use the formula =CEILING(4.42,0.05) to round prices up to the nearest nickel.
Excel Function: CEILING(number[,significance])
Parameters
- $number
- The number you want to round.
- $significance
- The multiple to which you want to round.
