verrallr@a	Posted - 04/08/2005 : 3:46:39 PM Origin Version (Select Help-->About Origin): 7.5 Operating System:NT It seems we cannot double-precision complex numbers. We can only get 7 signicant figures for each of the real and imaginary part. Is that correct? Richard.

verrallr@a	Posted - 04/08/2005 : 11:36:49 PM OK, thanks Easwar. In my code, when running Debug and watching Local Variables, it only appears as 7 digits. But, maybe thats just for space. I also used a small program in Origin's help, and it seemed to show only 7 digits. But, your example is conclusive. Thanks much, Richard.
easwar	Posted - 04/08/2005 : 4:38:37 PM Hi Richard, We tested and it works fine: #define CC_REAL_PART 0.9876543210987e300 #define CC_IMAGINARY_PART 0.1234567890123e-280 void test_complex() { complex cc; cc.m_re = CC_REAL_PART; cc.m_im = CC_IMAGINARY_PART; printf("real part = %17.13e\nimag. part = %17.13e\n", cc.m_re, cc.m_im); ASSERT(cc.m_re == CC_REAL_PART); ASSERT(cc.m_im == CC_IMAGINARY_PART); return; } Easwar OriginLab Edited by - easwar on 04/08/2005 5:00:06 PM
