atan

atenção

This function starts with a lowercase letter.

Description​

Get the inversed value of a tangent in degrees. In trigonometrics, arc tangent is the inverse operation of tangent. Notice that because of the sign ambiguity, the function cannot determine with certainty in which quadrant the angle falls only by its tangent value. See atan2 for an alternative that takes a fractional argument instead.

NameDescription
Float:valuevalue whose arc tangent is computed.

Returns​

The angle in degrees, in the interval [-90.0,+90.0].

Examples​

//The arc tangent of 1.000000 is 45.000000 degrees.

public OnGameModeInit()
{
    new Float:param, Float:result;
    param = 1.0;
    result = atan(param);
    printf("The arc tangent of %f is %f degrees.", param, result);
    return 1;
