function Tan ( const Number : Extended ) : Extended; Description The Tan function is a mathematical function giving the Tangent value of a Number value given radians. PI radians = 180 degrees Notes The System unit supports only the following angular functions: ArcTan Sin Cos Related commands ArcCos The Arc Cosine of a number, returned in radians ArcSin The Arc Sine of a number, returned in radians ArcTan The Arc Tangent of a number, returned in radians Cos The Cosine of a number Sin The Sine of a number Example code : Get the Tangent of 45 degrees var float : single; begin // The Tangent of 45 degrees = 1.0 float := Tan(PI/4); // = 180/4 = 45 degrees ShowMessage('Tan(PI/4) = '+FloatToStr(float)); end; Show full unit code Tan(PI/4) = 1
