Arithmetic Operations in Assembly Language
Arithmetic instructions in assembly language perform basic mathematical operations on data in registers or memory.
Adds the values of two operands and stores the result.
Subtracts the second operand from the first and stores the result.
Multiplies two operands and stores the result. The imul instruction is used for signed integers.
Divides the contents of a register by a specified value. The quotient is stored in the register, and the remainder in the special register edx.
Increment (inc) and Decrement (dec)
Increments or decrements the value of a register or memory location by 1.
Changes the sign of a value (multiplies it by -1).
Absolute Value (abs)
Computes the absolute value of a signed integer.
Arithmetic instructions can be used to perform a wide variety of tasks, such as:
- Calculating the sum of two numbers
- Finding the difference between two numbers
- Calculating the product of two numbers
- Calculating the quotient of two numbers
- Converting a number from one base to another
- Generating random numbers
- Performing statistical calculations
Arithmetic instructions facilitate fundamental mathematical operations on data, including addition, subtraction, multiplication, and division. These instructions directly manipulate registers or memory locations to perform computations and are essential for numerical data manipulation in low-level programming.
