The mikroPascal PRO for AVR implements fundamental trigonometry functions. These functions
are implemented as look-up tables. Trigonometry functions are implemented in integer format in
order to save memory.

function sinE3(angle_deg : word): integer;

The function returns the sine of input parameter.

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

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

Parameters: 

- 

angle_deg

: input angle in degrees 

Note: Return value range: -

1000..1000

.

Nothing.

var res : integer;
...
res := sinE3(45);  // result is 707
