WebIntel's math library (distributed with ICC), by comparison, can separately compute sin and cos in less than 100 cycles, using a software implementation that uses SSE instead of the x87 unit. A similar software implementation that computed both simultaneously could be faster still. – Stephen Canon Apr 21, 2010 at 15:50 3 WebCómo instalarlo con BlueStacks; Cómo instalarlo con Nox App Player; Cómo instalarlo IQ Math Game para PC con BlueStacks.
