Answer 1

divide number by 1 using int division:
example in python-

num = 17.9

print(int(num/1))

While your answer is specific to Python (and we do not know what the poster is after), it also does not quite make sense. Why would you need to divide at all? Just create the int:

decimal = 17.9
integral = int(decimal)
print(integral)

Answer 2

You have various tools from language to language.

What language are you coding in?

What type is your input? What type is your output?

Answer 3

a=10
b=4
print(a/b)
print(a//b)  # here we have use floor division it gives only integer part

output :

2.5

Answer 4

we can use built in functions like round() , floor() , ceil().for exact answer convert int to str and use break statement to terminate the loop

Answer 5

// in c
    // to get whole num
    float f = 420.69;
    printf("%d\n", (int) f);
    
    // to get remainder
    printf("%f\n", f - (int)f);

    // without using int to convert
    printf("%f\n",floor(f));
