A4.6.3.3 Calculate the burn rate to two significant figures
(to the nearest hundredth using conventional rounding rules,
that is, for 5 or higher, round up).
A4.6.3.4 Round the burn rate to the nearest tenth (that is,
round 0.15 up to 0.2).
想不通为什么要先四舍五入到两位有效数字,再四舍五入到1位有效数字....难道是在原始记录上记录两位有效数字,报告上出1位有效数字就可以了??大家是怎么看的呢?
