Swift如何迭代float [英] Swift how to iterate float

问题描述

我试图在Swift 2文档中找到它，但是找不到有关如何迭代浮点数的任何信息.新的快速迭代样式使我疯狂=)带有点等.

I tried to find this in Swift 2 docs, but can't find any info how to iterate floats. New swift iteration style make me crazy =) with dots and etc.

对于(i = 0; i< 100; i + = 0.5)

for (i = 0; i < 100; i+=0.5)

如何在Swift中编写它?

how to write it in Swift?

这不起作用，因为它是Double:

This does not work as it's Double:

for _ in 5.0.stride(100.0, by: 0.5) {
}

推荐答案

这与使用stride

快捷键2

for index in 0.0.stride(to: 99.5, by: 0.5) {
  print(index)
}

快捷键3

for index in stride(from:0.0, through: 99.5, by: 0.5) {
  print(index)
}
