units-of-measurement

问题 Is there a way to get distance between two objects in meters? I'm trying this right now units.displayType =#metric myDistance = distance aObject1 aObject2 label1.text = distance as string Of course this is giving me the distance between those objects but in units of 3dsmax... So if anyone knows a way or a formula i will be really grateful thank you 回答1: There is a whole topic in maxscript help dedicated to this, Units Struct - Accessing System and Display Units The piece of code you need

问题 I have a dataset that abbreviates numerical values in a column. For example, 12M mean 12 million, 1.2k means 1,200. M and k are the only abbreviations. How can I write code that allows R to sort these values from lowest to highest? I've though about using gsub to convert M to 000,000 etc but that does not take into account the decimals (1.5M would then be 1.5000000). 回答1: So you want to translate SI unit abbreviations ('K','M',...) into exponents, and thus numerical powers-of-ten. Given that

问题 I've got some data manipulation code which spits out csv at the end. I started upgrading it to add units of measure everywhere, but I now have a problem with my csv function: val WriteCSV : string -> 'a list array -> 'b list -> string -> unit (the parameters are fileName, column array, column headers, separator) Where I previously sent [|s;x;y|] to WriteCSV, I now have a problem, because I can't send [|skm; xmm; ymm|]. I tried writing a function for generically removing units of measure, but

问题 This question already has answers here : Pixels vs. Points in HTML/CSS (9 answers) Closed 2 years ago . I'm trying to understand the how CSS pixels relates to CSS points nowadays and what I've read is that one css point is a 3/4 pixel. Is that correct? And I can ignore the old idea that 1pt would be 1/72 of 1in because of difference in resolution and physical monitor sizes. If I want to convert css points to pixels a formula could look like this then? Xpt/75*100 = Ypx And if want to convert

问题 I have designed an application called CLegend, which allows to build a multicolumn legend, whose code is function CLegend(hax,numcol,Ley) %# Inputs % hax : handle of the axes object to which belongs the legend % numcol: number of columns for the legend % Ley: text strings (labels) for the legend set(hax,'Units','normalized','Position',[0.1 0.1 0.8 0.8]); set(hax,'Units','characters'); posAx = get(hax,'Position'); insAx = get(hax,'TightInset'); [legend_h,object_h] = legend(hax,Ley,'Units',

问题 Following on from this question, I still seem to be battling at the frontiers of what is possible, though I don't think that I'm doing anything particularly bleeding edge: type Vector2d = { X: float<'u>; Y: float<'u> } Gives me error FS0039: The unit-of-measure parameter 'u' is not defined. And type Vector2d = { X: float<_>; Y: float<_> } Gives me error FS0191: anonymous unit-of-measure variables are not permitted in this declaration. Is it the case that functions can handle 'generic' units

问题 I'm trying to use the UOMo java library in eclipse: http://www.eclipse.org/uomo I've installed it correctly (or at least I believe I have) via Help -> Install New Software..., dropped the repository link in, went through it all, was prompted to restart eclipse after installing the software. My problem is I have no idea how to use it. I've created a project and had a good dig around in the build path config. I can't find how to include UOMoin the project (obviously not doing is preventing my

问题 Has C#/the .NET library builtin routines or constants for converting e. g. millimetres to inches? If so, where can I find them? (I just do not want to produce duplicate code again and again.) 回答1: No, there are no such build in routines or constants in the framework. 回答2: Totally gratuiitous off topic reply F# has built in support for units. This is a random blog I just Binged Units Of Measure In F# 回答3: Here's a CodeProject sample that does unit conversion: http://www.codeproject.com/KB/cs

问题 How could I know in android whether to use metric or imperial? I haven't seen any option in Locale, and the only thing that comes to my mind is to use the locale.getCountry(); method and check whether the country is UK, US, ... But, is there an android's method to know it? Thanks in advance! 回答1: A more or less complete way to do this is this way: Kotlin: private fun Locale.toUnitSystem() = when (country.toUpperCase()) { // https://en.wikipedia.org/wiki/United_States_customary_units // https:

问题 Leaving aside whether we should use units of measure for unitless concepts like angles, suppose I have define degree and radian units in F# type [<Measure>] degree = static member ToRadians (d:float<degree>) : float<radian> = d * (Math.PI * 1.<radian>) / 180.0<degree> and [<Measure>] radian = static member ToDegrees (r:float<radian>) : float<degree> = r * 180.0<degree> / (Math.PI * 1.<radian>) I can use them relatively easily like 4.0<degree> |> degree.ToRadians It seems like extension
