Ifo1ando2then--两个操作数 都是数字?? If o1 and o2 then-- both operands are numeric? When there are 4 people, the number of operations is still 1. 如果两个操作数 有一个为double,则结果为double. If either operand is a double, the result is a double. 如果一个操作数 是double型,计算结果就是double型. If either operand is a double, the result is a double.
Subtracts second operand from the first A- B= -10. 具有混合类型操作数的运算符将整数操作数 转换为浮点. Operators with mixed type operands convert the integer operand to floating point. JNE is used for the comparison of operands . JEQ is used for the comparison of operands . The operand can't be null or undefined.Otherwise, the operand is not evaluated and the result is an integer constant. If both the operands are non-zero, then condition becomes true. If the operand is NaN, the result is also NaN. In this case, 2 and 3 are the operands . Note that this does NOT change the types of the operands themselves; This behavior generally results in comparing the operands numerically. Gcc程序接受选项options和文件名filenames作为操作数 。 The gcc program accepts options and file names as operands . A transaction can have one or more operations . 如果两个操作数 中的任何一个都是浮点数,则两个操作数 都将被评估为浮点数,结果将是一个浮点数。 If either operand is a float, then both operands are evaluated as floats, and the result will be a float. Constraints for these operands should use'n' rather than'i'. 表达式是使用操作数 的数据类型进行的,所以,例如,由两个整型数9与4相除:9/4。 The operation is conducted using the data type of the operands , so, for example, 9/ 4 gives 2 since 9 and 4 are ints. 无符号右移运算符的每个操作数 的类型必须是整数数据类型,否则会发生编译时错误。 The type of each operand of the unsigned right shift operator must be an integer data type, or a compile-time error occurs. 如果操作数 的大小兼容,则每个输入都会根据需要进行隐式扩展以匹配另一个输入的大小。 If the operands have compatible sizes, then each input is implicitly expanded as needed to match the size of the other. 相等和关系运算符确定一个操作数 是否大于、小于、等于或不等于另一个操作数 。 The equality and relational operators determine if one operand is greater than, less than, equal to, or not equal to another operand . 模数和赋值运算符,它使用两个操作数 来取模,并将结果分配给左操作数C%=A相当于C=C%A. Modulus AND assignment operator, It takes modulus using two operands and assign the result to left operand c%= a. 一元操作符有一个操作数 并且或是使用前缀符号(例如-x)或是使用后缀符号(例如x++)。 Unary operators take one operand and use either prefix notation(such as- x) or postfix notation(such as x++). In the example, 4 and 5 are called operands , and"+" are called operators. 第一个操作码aload_0将this引用值从局部变量表的索引0压入到操作数 栈。 The first opcode, aload_0, pushes the value from index 0 of the local variable table onto the operand stack. 如果两个操作数 都是数字,它们首先被转换为一个共同的类型。 If both operands are numbers, they are first converted to a common type.
