◆ tpt_atan_q15()

q15_t tpt_atan_q15 ( q15_t aInData )

Arctan value of floating-point input.

Calculate the arctangent value of a given number.

Parameters

[in] src the input value.

Returns: arctan value of the input.

Function notes: The input argument is tangent of the radian to be returned. It is scaled as Q(RES_LOGN).15-(RES_LOGN). For example, it is Q8.7 if RES_N = 256. The returned value falls in the range of [-PI / 2, PI / 2) scaled as depending on global symbol FOUR_PI_RANGE: 1> defined: [-0.25, 0.25) 2> otherwise: [-0.5, 0.5)
