out of this dimension, you may not even be aware of this restriction. However, the abstract dimensions of DSL (domain-specific language) such as SQL, HTML, CSS, and make are customized for specific fields. From these abstract perspectives, the problem is often the easiest, therefore, DSL is more convenient than general programming languages in solving problems in specific fields. Generally, non-General lan

Domain-specific language (DSL) is a hot topic in recent years. One trend of DSL is to integrate DSL into common languages.
Many years ago, if we wanted to use DSL in a common language, we usually needed strings, such as database access. We had to splice
Digital Subscriber line or DSL is a technology that provides digital connectivity via copper or local telephone networks. Its history dates back to the 1988, when an engineer at Bell Labs designed a method that allows digital signals to be loaded into unused bands on a telephone line, which provides data communication on a regular telephone line without compromising the voice service. But Bell's management is not enthusiastic about this, because if us
Through the overall compression technology, COS can significantly reduce the storage space occupied by data, thereby improving the storage efficiency of the physical disk.
The storage-capacity optimization technology (cos,capacity optimized Storage) in data domain can significantly reduce the capacity required to backup media by splitting and comparing data content with the principle of compression.

Returns the cosine of a corner.
Cos(number)
The number argument can be any valid numeric expression that represents a corner as radians.
Description
The Cos function takes a corner and returns the ratio on both sides of the right-angled triangle. This ratio is the ratio of the length of the adjacent side of the triangle to the length of the hyp
side length divided by the angle of the adjacent side length of the quotient. The range of values is between-PI/2 and PI/2 radians. To convert the angle to radians, multiply the angle by pi/180. To convert radians to angles, multiply radians by 180/pi.
Note: Atn is the inverse trigonometric functions of tan, and the value of tan is the angle, which returns the ratio of two sides of the right-angled triangle. Instead of confusing the Atn with the cotangent function, the cotangent function value

A few months ago, bloggers were concerned about DSL, so I thought, I created some DSL in gac.codeplex.com, so I said it today.
Creating a DSL I'm afraid it's the first time a lot of people have ever designed a language. The first time I did this was when I wrote this stupid arpg in high school. It was a very simple scripting language, and it was similar to a com
