Question

write
a program to accept 10 different decimal num.
bers in a single dimensional array (say A) Truncate
the fractional part of each number of the array A
and store their integer part in another arday (say B)​

Answer 1

Answer:

Anonymous has correctly said that casting a float to an integer drops the fractional part. However, not all languages play nice like this. Java forces you to jump through a few more hoops.

class MathTest

{

public static void main(String args[])

{

double a = 5.3;

int b = (int)Math.floor(a);

double c = a - b;

System.out.println("Integral = " + b);

System.out.println("Fractional = " + c);

}

}

Expect some error in the fractional part.

Edit : The above solution is for positive numbers only. To make it work for both, you can replace line 6 with

int b = a>0 ? (int)Math.floor(a) : (int)Math.ceil(a);
