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
