1. trunc (): — This function is used to remove the entire decimal part of a floating point number and return an integer without the decimal part.
2 … ceil (): — This function is used to output the smallest integer greater than a given number .
3. floor (): — This function is used to output the largest integer less than the specified integer .
Output:
The integral value of number is: 3 The smallest integer greater than number is: 4 The greatest integer smaller than number is: 3
Setting Accuracy
There are many ways to set the correct a number of floating point values. Some of these are discussed below.
1. Using “%” : — the “%” operator is used for formatting as well as setting precision in python. This is similar to the “printf” statement in C .
2. Using format (): — is another way to format a string to set precision.
3. Using round (x, n): — This function takes 2 arguments, a number and the number to which we want to round the decimal part.


Output:
The value of number till 2 decimal place (using%) is: 3.45 The value of number till 2 decimal place (using format ()) is: 3.45 The value of number till 2 decimal place (using round ()) is: 3.45
