McLaurin_F32(r, rStart, rEnd)

Description

McLaurin series calc: rStart and rEnd (inclusive) defines the start float and the end floats, say you have three r0, r1, r2, then calculation is: r = r0rr + r1*r + r2.

r is the buffer position used for the indeterminate value and for the result.

Return
Nothing

Code Example

The following code example uses the McLaurin_F32 function.

The SMK900.evi file used for this example can be downloaded at the bottom of this page.
/* Example Code
* LinInterpol_F32
*
* get buffer indexes rS, rE and r
* set buffer in memory
* mclaurin value at r
* return 0x00 (lookup pas ok) or 0x01 (lookup ok)
*
