Trigonometry Library
The mikroBasic PRO for PIC 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 |
sub function sinE3(dim angle_deg as word) as 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 |
dim res as integer ... res = sinE3(45) ' result is 707 |
cosE3
| Prototype |
sub function cosE3(dim angle_deg as word) as 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 |
dim res as integer ... res = cosE3(196) ' result is -961 |
