It also includes methods for performing mathematical task that are normally impossible or too complex to perform using standard mathematical operators (+, -,*, and /) such as calculating sine or cosine values.Th
6.3 数学操作符(Math Operators) Cg语言对向量的数学操作提供了内置的支持,Cg中的数学操作符有:*乘法、/除法、-取反、+加法、—减法、%求余、++、——、*=、/=、+=、-=。后面四种运算符有时被归纳入赋值操作符,不过它们实际上进行数学计算,然后进行赋值, 所以这里也放入数学操作符中进行说明。 在文献【2】...
Arithmetic operatorsare symbols that indicate a mathematical operation and return a value. In the equation3 + 7 = 10, the+is syntax that stands for addition. JavaScript has many familiar operators from basic math, as well as a few additional operators specific to programming. Here is a referen...
=in their tests for equality and non-equality. These are valid operators in JavaScript, but they differ from===/!==. The former versions test whether the values are the same but not whether the values' datatypes are the same. The latter, strict versions test the equality of both the ...

One of the language design decisions in JavaScript has followed in C's footsteps by providing implicit type conversions based on what operators you give it. For example in JavaScript, you can addtrue + trueto get2. While it may be convenient in some cases, this has been a pain point for...
