Arithmetic Operators 算术运算符以数值(字面量或变量)作为其操作数,并返回一个单个数值。标准算术运算符是加法(+),减法( - ),乘法(*)和除法(/)。加法(+) 加法运算符的作用是数值求和,或者字符串拼接。语法 代码语言:javascript 复制 Operator: x + y ...

// Operators act on values (the operands) to produce a new value. // Arithmetic operators are some of the simplest: 3 + 2 // => 5: addition 3 - 2 // => 1: subtraction 3 * 2 // => 6: multiplication 3 / 2 // => 1.5: division points[1].x - points[0].x // => 1:...

Unary operators modify the value of a single operand to produce a new value. In JavaScript, the unary operators all have high precedence and are all right-associative. The arithmetic unary operators described in this section (+, -, ++, and --) all convert their single operand to a number...
For instance, JavaScript might convert a string to a number during an arithmetic operation. While this can simplify some code, it can also lead to unexpected results if not handled carefully.Explicit Typing: Unlike implicit typing, explicit typing involves manually converting a value from one type...
If you don't want to automatically change value types in arithmetic operations, disable this option and keep in mind that your script should care about slowness if there are too many overflows. On the other hand, operations on int, long are faster than double. If you want to explicitly ha...
Note that if you use bitwise operators in JavaScript, you are further limited to 32-bits of ordinal precision.This sample code sums two numbers and will be used to test the conversion of 64 bit values.JavaScript Copy function playWith64BitValues(a64, b64) { // Sum two numbers to ...
