artificial intelligence - What is the meaning of <- in AI? -

-

I have seen lots of AI related items in the symbol & lt; -. For example, 

  delta & lt; - 0x & lt; - x + 1

etc.

I always assumed its meaning = (Assigment), but perhaps they have a meaning that is slightly different from the segment, I think?

Thank you

This is an assignment. It removes ambiguity that "=" The symbol adds, because this symbol is often overloaded to test equality.

It makes it very clear that the thing on the left side is being matched, corrected, integrated, or otherwise equals it.

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends.
