units-of-measurement

问题 So, I've tried to get around this in various ways, but I just can't make this work. Is there any way to make a list that contains values of varying units of measurement (all based on floats)? For example: let myList = [0.07<ms>; 0.9; 7.2<mm>;] As they are treated as different types, you cannot put them in the same list. I tried declaring the list as let myList : float<_> list = ... , and giving dimensionless numbers a unit of measurement, but I still got a typing error: expecting float<'u>

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 7 years ago . In this question "unit(s)" refers to "unit(s) of measure" used in physical quantities. I want to safely parse an untrusted user input string containing physical quantities (e.g. '23 kg'). I'd like to use one of

问题 I want to use metric and Imperial distance units in an application. One way of doing this is tagging a number with the unit. I don't want to go this route. I want to use one internal representation that can exactly hold imperial down to 1/64 of an inch and 0.2mm. I have come up with 8128 RSU (really small units) that is divisible by 64 and 254, which does what I want. This is close to 2^13, and it has got me wondering if there is a more optimal way of doing this? Any ideas? 回答1: A slightly

问题 I am working on sentence category detection Problem. Where each sentence can belong to multiple categories for Example: "It has great sushi and even better service." True Label: [[ 0. 0. 0. 0. 0. 1. 0. 0. 0. 0. 0. 1.]] Pred Label: [[ 0. 0. 0. 0. 0. 1. 0. 0. 0. 0. 0. 1.]] Correct Prediction! Output: ['FOOD#QUALITY' 'SERVICE#GENERAL'] I have implemented a classifier that can predict multiple categories. I have total 587 sentences that belongs to multiple categories. I have calculated the

问题 I am trying to keep track of the bounding Rect for a child TextView inside of a class extending LinearLayout I am using View.getGlobalVisibleRect(Rect) in order to get the TextView's bounding box relative to its parent. It works great on some devices, but there is obviously some kind of unit issue going on on other phones. Simple example of what I'm seeing: //Extended LinearLayout's onDraw protected void onDraw(Canvas canvas){ super.onDraw(canvas); TextView tv = (TextView)findViewById(R.id

问题 I currently have: jquery $(document).ready(function () { $('.span-fix').each(function(){ /* Do this for each extended input */ var wide = $(this).width(), /* create a variable that holds the width of the form */ label = $(this).prev('.add-on').width(); /* create another variable that holds the width of the previous label */ $(this).width( wide - label ); /* subtract the label width from the input width and apply it in px */ }); }); html <div class="input-prepend"> <span class="add-on"

问题 I'm very new to F# and am intrigued by the Units of Measure functionality and have a rough idea of how it works normally, but would like to know if it's possible to bind measures to values where we don't know what the measure will be until the code is executing? The practical example I'm looking at is binding floats as currency values where the unit of measure is inferred from a database lookup. Let's assume that the measures for each currency (USD, EUR, AUD, etc) are declared normally: [

问题 I was scanning some stylesheets when I noticed one which used a linear-gradient with rgba() color-stops in which the rgba numbers used multiple instances of 0 instead of just a single 0 : background-image:linear-gradient(to top left, rgba(000,000,000,0.1),rgba(100,100,100,1)); I hadn't seen multiple zeroes (instead of a single zero) occupying a single slot in the rgb/a color space before, but confirmed on CodePen this is valid. I then looked up the W3C definition of number here. To make a

问题 I am beginning to learn how to use units of measure in F# but I haven't found the answer to this simple question yet. How do you print the resultant units after a calculation. I know that FSI prints them so they should be available somehow. For example: [<Measure>] type m;; [<Measure>] type s;; let d = 10<m>;; val d : int<m> = 10 let t = 2<s>;; val t : int<s> = 2 I want to do something like this: printfn "Results: %A %A" (d / t) (UOM (d / t));; "Results: 5 m/s" Thanks in advance 回答1:
