# How do you determine if a number is odd in an assembly?

## How do you determine if a number is odd in an assembly?

checks if the lowest bit of AL/AX/EAX/RAX is set. If it is, the number is odd. where all bn values are either zero or one. The only way to get an odd number is if the least significant bit ( b0 ) is 1.

How do you find the factorial of a number in 8086?

Algorithm –

1. Input the Number whose factorial is to be find and Store that Number in CX Register (Condition for LOOP Instruction)
2. Insert 0001 in AX(Condition for MUL Instruction) and 0000 in DX.
3. Multiply CX with AX until CX become Zero(0) using LOOP Instruction.
4. Copy the content of AX to memory location 0600.

### What is assembly language programming 8086?

The assembly programming language is a low-level language which is developed by using mnemonics. The microcontroller or microprocessor can understand only the binary language like 0’s or 1’s therefore the assembler convert the assembly language to binary language and store it the memory to perform the tasks.

How do you determine if an odd assembly is even?

we can determine one number is odd or even by checking only the LSb. When LSb is 1, the number is odd, otherwise it is even.In this program we are taking a number from memory and then ANDing 01H with it. if the result is nonzero, then the number is odd, otherwise it is even.

#### How do you check if a number is even or odd in assembly language?

If you want to check whether a given number is odd or even, a simple test would be to check the least significant bit of the number. If this is 1, the number is odd, else the number is even.

How do you check if a number is even or odd in MIPS?

If the number is evenly divisible by 2, the remainder will be 0 and the number is even. If the number is not evenly divisible by 2, the remainder is 1 and the number is odd.

## How do you find the factorial of a number?

To find the factorial of a number, multiply the number with the factorial value of the previous number. For example, to know the value of 6! multiply 120 (the factorial of 5) by 6, and get 720.

How do you solve 100 factorial?

Answer to puzzle #19: 100 Factorial

1. When one of the things being multiplied ends in zero itself.
2. A number ending in 5 multiplied by an even number.
3. 25, 50 and 75 when multiplied by some of the small numbers available eg (4, 2 and 6) generate an extra zero.

### How do you write and run an assembly program?

1. Copy the assembly code.
