WebFeb 14, 2014 · The IQMath sine table is in Q30 (2 integer, 30 fractional bits) format spanning 0 to 2pi in increments of sin (2pi/512). The IQMath sin () uses a taylor series approximation and is accurate to about 29 bits, sgen uses linear interpolation. 0 Brian I. over 9 years ago in reply to Vishal_Coelho Intellectual 340 points Hi Vishal, Web首先在main函数前增加IQ格式的变量定义： _iq IQresult =_IQ (1.0); _iq IQsource; 在main函数调用IQmath库中的任意函数，这里我调用了IQsin ()函数进行测试： IQresult =_IQsin (IQsource); 通过实际debug，计算结果与预期相符。 三.

WebSep 6, 2013 · sin(-A) = -sin(A) This made it so I only needed to calculate sin and cos for one half of the circle. I also setup pointers to my output arrays and this also sped up my calculations. I'm not sure of this, but I believe that my compiler vectorized my calculations. A third was to use: sin(A+dA) = sin(a)*cos(dA) + cos(a)*sin(dA)
