请帮忙,不知哪里出了问题 ?双精度浮点数

guod

我想从 VAL 表中取出双精度浮点数 (vlax-vbDouble), 1.51571656652214, 但为何只能得到1.51572 ,请帮忙,不知哪里出了问题 ?

(setq ddd (vlax-safearray-get-element val 1 20))

(print ddd ) , #<variant 5 1.51571656652214>

(setq ddd (vlax-variant-value (vlax-safearray-get-element val 1 20)))

(print ddd ) 1.51572

(rtos ddd 2 14)再看看,其实没变,只是显示而已
