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

Usage:
#include <math.h>
y = floor( x );
Where:
double x, y;
Description:
"floor" returns the largest integer (represented as a double precision number) that is less than or equal to "x".
#include <math.h>
y = floor( x );

roundup() function preforms just rounding the value 10.5 to 11
and roundto() function performs like specification if u want to display 2 decimal r three decimal. its like 123.345 u want it for 0 decimal means it displays 123. and for 1 its displays 123.3 like wise it performs

What is the difference between roundup() and ceil()?
As both are doing the same thing. ex:ceil(10.5) rounds to a next integer value.i.e.11.even roundup() do the same thing.then what is the difference between these two?

@sasi.
Here you are saying that for >. 5 then only the valu will round to next higest integer but if we give as ceil (2. 1) also we get ans as 3 then how?
And for roundup value is it >. 5 or may anything?
