Trigonometry Library
The mikroPascal PRO for 8051 implements fundamental trigonometry functions. These functions are implemented as look-up tables. Trigonometry functions are implemented in integer format in order to save memory.
Library Routines
sinE3
| Prototype |
function sinE3(angle_deg : word): integer; |
|---|---|
| Returns |
The function returns the sine of input parameter. |
| Description |
The function calculates sine multiplied by 1000 and rounded to the nearest integer: result := round(sin(angle_deg)*1000) Parameters:
 Note :
Return value range: -1000..1000
|
| Requires |
Nothing. |
| Example |
var res : integer; ... res := sinE3(45); // result is 707 |
cosE3
| Prototype |
function cosE3(angle_deg : word): integer; |
|---|---|
| Returns |
The function returns the cosine of input parameter. |
| Description |
The function calculates cosine multiplied by 1000 and rounded to the nearest integer: result := round(cos(angle_deg)*1000) Parameters:
Note :
Return value range: -1000..1000.
|
| Requires |
Nothing. |
| Example |
var res: integer; ... res := cosE3(196); // result is -961 |
