Description

Get the inversed value of an arc tangent in radians.

Name Description
Float:value the input in arc tangents.

Returns

The radiant of the angle in radians.

Examples

//This function returns radiants. Because most SA-MP functions use degrees, it is advised to convert them using the formula: result = atan (param) * 180 / PI

public OnGameModeInit()
{
	new Float:param, Float:result;
	param = 1.0;
	result = atan(param) * 180 / 3.14159265; //1 radian equals 180 degrees. 3.14... is used to define PI.
	printf ("The arc tangent of %f is %f degrees\n", param, result );
	return 0;
