PowerShell Round & Format Float to max 2 decimals?

由 最后都变了- 提交于 2020-12-30 04:56:24
问题 I found lots of stuff to format floats to common known numbers, but how can I format a float to a max of 2 decimals, but only if the decimals are needed? Examples: 1.11 # not 1.111 1.12 # it was 1.116 (round up) 1.1 # not 1.10 1 # not 1.00 if I do $('{0:N2}' -f $flt) I get 1.00 # :( Thanks in advance! 回答1: Use [math]::round , ie: [math]::round(1.111,2) will return 1.11 and [math]::round(1.00,2) yields 1 回答2: You can use the # character in a custom numeric format string to include non-zero

文章目录 什么是cmder 安装cmder 让cmder便于使用 将cmder添加到右键菜单中 在设置中添加语言环境 设置默认使用cmd、PowerShell还是bash 调节背景的透明度 添加 ll 命令 常用快捷键 Q&A 解决文字重叠问题 修改命令提示符号`λ` 什么是cmder cmder 是一款Windows环境下非常简洁美观易用的cmd替代者，它是一个跨平台的命令行增强工具，可以集成windows batch, power shell, git, linux bash等多种命令行于一体，支持了大部分的Linux命令，比如 grep, curl(没有 wget)，vim，grep，tar，unzip，ssh，ls，bash，perl等。还可以通过自定义，让它更方便。最重要的是颜值也比Windows自带的cmd好得多，支持文字颜色区分。 Windows自带的cmd有哪些缺点 复制文本，不能直接用鼠标拷贝，还需要多一道菜单操作；而且，还只能块状拷贝，而不是按行字符，极其不便 不支持多Tab页，多窗口管理不便 安装cmder 在 cmder官网 下载Full版本（内建Git for Windows），直接解压便可以使用啦 让cmder便于使用 将cmder添加到右键菜单中 在 PATH 中增加 Cmder.exe 所在目录（如D:\Program Files\cmder）

问题 I have a PowerShell script that does the following: Upgrades an old Visual Studio solution using devenv.exe. Builds the upgraded Visual Studio solution using MSBuild. If I run this script, I get an error stating "MSBUILD : error MSB3428: Could not load the Visual C++ component "VCBuild.exe". To fix this, 1) install the .NET Framework 2.0 SDK, 2) install Microsoft Visua l Studio 2005 or 3) add the location of the component to the system path if it is installed elsewhere." What is strange to me

How does Powershell know where to find modules for import?

由 末鹿安然 提交于 2020-12-30 02:34:05
问题 I am really at beginner level for working with commandlets and powershell stuff. I am invoking commandlets from C# using PowerShell API. I saw strange behaviours. While on different threads on stackoverfow, people explicitly importing modules using Import-Command or PSImportModule method, I can see if there is an assembly at $env:PSModulePath available already, it is automatically loaded. Does this behaviour is by default or due to criteria configurations which i m overlooking. I am running

How to run a PowerShell Script after Inno Setup installer

由 依然范特西╮ 提交于 2020-12-30 01:34:36
问题 I have a PowerShell script that modifies some preference files that I'm trying to have run after my Inno Setup installer is completed. Haven't found a working solution for this yet. My goal is to embed this in the file, or code, so I don't have to ship multiple files, just the installer. Thanks! 回答1: To execute a command after an installation finishes, add an entry to [Run] section. If the PowerShell code is trivial, you can executed it without any script file directly from PowerShell command
