How would you round off a value from 1.66 to 2.0?
Answer: Option
Explanation:
/* Example for ceil() and floor() functions: */
#include<stdio.h>
#include<math.h>
int main()
{
printf("\n Result : %f" , ceil(1.44) );
printf("\n Result : %f" , ceil(1.66) );
printf("\n Result : %f" , floor(1.44) );
printf("\n Result : %f" , floor(1.66) );
return 0;
}
// Output:
// Result : 2.000000
// Result : 2.000000
// Result : 1.000000
// Result : 1.000000

What is mean by ceil and round to? What is the difference between ceil, roundto and roundup?

Friends there is no any functions like roundup() and roundto() in C language.

@Sasikumar.
You said that ceil() - This function works as follows: if the value is greater than or equal to (_.5) then, it round off a value into the next integer value.
Otherwise it round off into before integer value of the given float number, but in the explanation part they have given an example in that the o/p of ceil(1.44) is 2 how can it be? it was suppose to b 1 right?

Please tell me. We use roundto() instead of roundup(). Is it possible?

Here you are saying that for >. 5 then only the value will round to next highest integer but if we give as ceil (2.1) also we get ans as 3 then how?

#include<stdio.h>
int main()
{
int x;
x=ceil(1.2) ;
printf("%f ",x);
printf("%f",ceil(1.2));
return 0;
}
Difference b/w two statement in this program.
1. x=ceil(1.2) ;
2. printf("%f",ceil(1.2));
int main()
{
int x;
x=ceil(1.2) ;
printf("%f ",x);
printf("%f",ceil(1.2));
return 0;
}
Difference b/w two statement in this program.
1. x=ceil(1.2) ;
2. printf("%f",ceil(1.2));

Friends ceil(1.00000001)==>2.0 and floor(1.99999999)==>1.0
And there are no functions like roundup and roundto.
I think it help's to you.

Give some examples of ceil() and floor() and roundup() and roundto().

@Maya.
The answer will be 2 because ceil() function only display the next higher integer for the given no.
