Trigonometry Library
The mikroC PRO for ARM 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 |
int sinE3(unsigned angle_deg); |
|---|---|
| Description |
The function calculates sine multiplied by 1000 and rounded to the nearest integer:
result = round(sin(angle_deg)*1000)
|
| Parameters |
|
| Returns |
The function returns the sine of input parameter multiplied by 1000. |
| Requires |
Nothing. |
| Example |
int res; ... res = sinE3(45); // result is 707 |
| Notes |
Return value range: |
cosE3
| Prototype |
int cosE3(unsigned angle_deg); |
|---|---|
| Description |
The function calculates cosine multiplied by 1000 and rounded to the nearest integer:
result = round(cos(angle_deg)*1000)
|
| Parameters |
|
| Returns |
The function returns the cosine of input parameter multiplied by 1000. |
| Requires |
Nothing. |
| Example |
int res; ... res = cosE3(196); // result is -193 |
| Notes |
Return value range: |
