也许一行数学？ [英] One line of math perhaps?

问题描述

我有一个简单的数学函数我想要预成型。对于每10个单位选择一个字段，我需要减去3个单位。因此，如果选择了30个单位，那么就会从那30个单位中减去9个单位，然后再将其放入其休息场。


希望它不是太复杂，但是我可以理解它时间。

I have a somewhat simple math function i would like to preform. For every 10 units selected into one field, I need 3 subtracted from. So if 30 units is selected, then 9 is subtracted from that 30 before being dumped into its resting field.

Hopefully its not too complicated, but it was more then I could figure out at the time.

这是按比例计算的吗？

或者是它在减去任何值之前达到10的倍数是必要的（换句话说，值29返回8.7或简单地为6）？

Is this on a pro rata basis?
Or is it necessary to reach a multiple of ten before any is subtracted (in other words does a value of 29 return 8.7 or simply 6)?

或者是否有必要在减去任何值之前达到十的倍数（换句话说，值29是否返回8.7或只是6）？

每10个单位，我需要减去3个单位。如果选择9或8个单位，则不需要进行任何操作，除此之外保持9或8.如果11完成，那么我需要减去3然后添加1。

Every 10 units, i need to subtract 3 Units. If 9 or 8 units is selected, then nothing needs to be done, other then keeping that 9 or 8. If 11 is done, then i need the 3 subtracted for the 10 then added with 1.
