kandi X-RAY | zero Summary

zero is a TypeScript library typically used in User Interface, Graphics applications. zero has no bugs, it has no vulnerabilities and it has medium support. However zero has a Non-SPDX License. You can download it from GitHub.

Zero is a small graphics demo that implements a 3D renderer in JavaScript and renders it's output to a terminal via nodejs' stdout. Zero was written for fun and to push JavaScript performance. ASCII rendering has been tested on Windows, OSX and Linux terminals. ANSI 24-bit true color rendering has been tested on Cygwin (Windows) and Linux Mint terminals, but should work on most terminals that support true color. This project and associative materials are offered as is to anyone who may find them of use.

            The n2 - n1 in the case of a negative number as a result when converted to bool will yield true. So n1 turns out to be less than n2. That's why it is a bad practice to use ints in such Boolean context.

            Yes, as stated in the documentation:

            ...comparison function object which returns ​true if the first argument is less than the second

            But the implementation of the comparison here leads to failure. Try this and see for yourself:

            Iterating over a vector does not update the objects
            Asked 2021-Jun-15 at 23:31

            I'm learning C++ and have come to a bit of a halt. I'm trying to iterate over a vector with a range-based for loop and update a property on each of the objects that belong to it. The loop is inside of an update function. The first time it fires, it works fine; I can see the property gets updated on each member of the vector. However, the next time the for loop is initiated, it's still updating the original data, as if the previous run did not actually update the source values. Is my range declaration configured correctly? Pointers are still a bit of a mystery to me. In general I'd be very thankful for any help!

            Vector3 position = point.position; makes a copy of point.position. The following code then updates this copy, which in turn is thrown away when it goes out of scope at the end of the if statement.

            The solution is simple enough - use a reference instead: Vector3 &position = point.position;. The rest of the code can be left as-is.

            Surprisingly, this is not undefined behavior.

            Static initialization [basic.start.static]

            Constant initialization is performed if a variable or temporary object with static or thread storage duration is constant-initialized. If constant initialization is not performed, a variable with static storage duration or thread storage duration is zero-initialized. Together, zero-initialization and constant initialization are called static initialization; all other initialization is dynamic initialization. All static initialization strongly happens before any dynamic initialization.

            Important parts bold-faced. "Static initialization" includes global variable initialization, "static storage duration" includes global variables, and the above clause is applicable here:

            be aware I don't have a Windows machine against which to try this, so it's just "best effort"

            As best I can tell, your problem is because you are trying to recreate the behavior of win_shell by "manually" invoking that improperly quoted cmd.exe /c business, ending up with cmd.exe /c "cmd.exe /c whatever"; dialing up the ansible verbosity -vv could confirm or deny that pattern

            Also, the win_shell docs say to use win_command: unless you have a shell redirect need, which as written your task does not.

            Barring the undefined behavior which can be easily be fixed, you're seeing the effect of denormal numbers. They're extremely slow (see Why does changing 0.1f to 0 slow down performance by 10x?) so in modern FPUs there are usually denormals-are-zero (DAZ) and flush-to-zero (FTZ) flags to control the denormal behavior. When DAZ is set the denormals will compare equal to zero which is what you observed

            Currently you'll need platform-specific code to disable it. Here's how it's done in x86:

            First of all: a Rat with a denominator of 0 is a perfectly legal Rational value. So creating a Rat with a 0 denominator will not throw an exception on creation.

            I see two issues really:

            • how do you represent a Rat with a denominator of 0 as a string?
            • how do you want your program to react to such a Rat?

            When you represent a Rats as a string, there is a good chance you will lose precision:
