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

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

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".

I take daily life exa.
Ceil mean ceiling fan i.e. Upper limit
Floor mean ground i.e. Lower limit
Here I take upper limit mean +positive infinity n lower is -neg
Infinity
During ceil function we round value toward positive value
i.e. 3.2=4
3.6=4
2.1=3

ceil(1.44) = 1.00 and roundup(1.44) = 1.00 so both are same?

Floor : It is used to eliminate the float(decimal)numbers that means if the value is 3.50 means the result is 3.00. It eliminate the .50.
Ceil : It is used to round the next integer value that means if the value is 3.50 or 3.4 the result is 4.
Round : It is used to round up or round down the float numbers based on the numbers. If the value is <3.5 then the result is 3 and >= 3.5 then v will get 4.

I understood about ceil and need more clarity about floor().
Can anyone explain me about floor() with an suitable example?
