This is true on a FPU-less, JIT-less G1 and a Nexus One with an FPU and the JIT. (Of course, absolute speed difference between those two devices is about 10x for arithmetic operations.)
通常的经验是,在Android设备中,浮点数会比整型慢两倍,在缺少FPU和JIT的G1上对比有FPU和JIT的Nexus One中确实如此(两种设备间算术运算的绝对速度差大约是10倍)
So if there's a difference in run time, it's not because of the arithmetic code.
所以如果在运行时间上有差异,那么不是因为算术代码)。
