function cosE3(angle_deg : word): integer;

The function returns the cosine of input parameter.

The function calculates cosine multiplied by 1000 and rounded to the nearest integer:

- 

result := round(cos(angle_deg)*1000)

Parameters: 

- 

angle_deg

: input angle in degrees 

Note: Return value range: -

1000..1000

.

Nothing.

var res: integer;
...

res := cosE3(196);  // result is -193
