sin
sin(): Real;
The sin method of the Real primitive type returns the sine of the receiver. The receiver value represents an angle in degrees, and the resulting value is always in the range -1 through 1.
The following example shows the use of the sin method.
vars realValue : Real; begin realValue := 340.5; // Defines the variable value write realValue.sin; // Outputs -0.333806859233771 end;
