Truncating a number without rounding
显示 更早的评论
Is it possible to truncate a number in matlab without rounding it to the first decimal point? for example, 5.17 I want it to be 5.1 and not 5.2 Thanks

For negative values you need to figure out whether you want -5.17 to go to -5.1 or to -5.2 . If you want the truncation to be "at most" the original value, then you would use floor(a*10)/10 . If you want the truncation to be "closer to 0" then you would use fix() like Azzi shows.
