integer division

基本解释

It's doing integer division.
這是整數的除法。
Because filenum will always be less than filecount, the integer division filenum/filecount will always produce zero, so each iteration of the loop will echo
由於 filenum 始終小於 filecount，整數除法 filenum/filecount 將始終生成 0，因此每次疊代循環都將生成
In such cases, integer division and modulus operations are performed in software —something to think about if you're designing a hash table or doing lots of math.
這種情況下，整型除法和求模運算是通過軟件實現的，就像儅你設計Hash表，或是做大量的算術那樣。
