Q:

# We want to round off x, a Float to an Int value. The correct way to do so would be

 A) Y = ( int ) ( x + 0.5 ) ; B) Y = int ( x + 0.5) ; C) Y = ( int ) x + 0.5; D) Y = ( int ) ( ( int ) x + 0.5 )

Answer:   A) Y = ( int ) ( x + 0.5 ) ;

Explanation:

Rounding off a value means replacing it by a nearest value that is approximately equal or smaller or greater to the given number.

y = (int)(x + 0.5); here x is any float value. To roundoff, we have to typecast the value of x by using (int)

Example:

#include

int main ()

{

float x = 2.6;

int y = (int)(x + 0.5);

printf ("Result = %d\n", y );

return 0;

}

Result : 3
