Python Program for trunc() Function

In the previous article, we have discussed Python Program for ldexp() Function
trunc() Function in Python:

The math.trunc() method returns the integer part of a number that has been truncated.

Note: Please keep in mind that this method will NOT round the number up or down to the nearest integer, but will simply remove the decimals.

Syntax:

math.trunc(x)

Parameters:

x: This is required. It is a number. The number from which you want to remove the decimal point(truncate). If the value is not a number, a TypeError is returned.

Return Value: Returns an int value that represents a number’s truncated integer parts.

Examples:

Example1:

Input:

Given first number = 870.26
Given second number = -11.56

Output:

The truncated value of the given first number  870.26  =  870
The truncated value of the given second number  -11.56  =  -11

Example2:

Input:

Given first number = 80.432
Given second number = 22.4

Output:

The truncated value of the given first number  80.432  =  80
The truncated value of the given second number  22.4  =  22

Method #1: Using Built-in Functions (Static Input)

Approach:

Import math module using the import keyword.
Give the list as static input and store it in a variable.
Give the first number as static input and store it in another variable.
Apply math.trunc() function to the given first number to remove the decimal part and give only the integer part of the given number. (truncate)
Store it in another variable.
Print the truncated value of the given first number.
Similarly, do the same for the other number.
Apply math.trunc() function to the given list element and print it.
The Exit of Program.

Below is the implementation:

# Import math module using the import keyword.
import math
# Give the list as static input and store it in a variable.
gvn_lst = [12.005, 11.89, 30.224]
# Give the first number as static input and store it in another variable.
gvn_numb1 = 870.26
# Apply math.trunc() function to the given first number to remove the decimal
# part and give only the integer part of the given number. (truncate) 
# Store it in another variable.
trnc_numb = math.trunc(gvn_numb1)
# Print the truncated value of the given first number.
print("The truncated value of the given first number ",
      gvn_numb1, " = ", trnc_numb)
# similarly do the same for the other number.
gvn_numb2 = -11.56
trnc_numb2 = math.trunc(gvn_numb2)
print("The truncated value of the given second number ",
      gvn_numb2, " = ", trnc_numb2)
# Apply math.trunc() function to the given list element and print it.
print(
    "The truncated value of the given list element ", gvn_lst[2], " = ", math.trunc(gvn_lst[2]))

Output:

The truncated value of the given first number  870.26  =  870
The truncated value of the given second number  -11.56  =  -11
The truncated value of the given list element  30.224  =  30

Method #2: Using Built-in Functions (User Input)

Approach:

Import math module using the import keyword.
Give the list as user input using list(),map(),input(),and split() functions.
Store it in a variable.
Give the first number as user input using the float(input()) function and store it in a variable.
Apply math.trunc() function to the given first number to remove the decimal part and give only the integer part of the given number. (truncate)
Store it in another variable.
Print the truncated value of the given first number.
Similarly, do the same for the other number.
Apply math.trunc() function to the given list element and print it.
The Exit of Program.

Below is the implementation:

# Import math module using the import keyword.
import math
# Give the list as user input using list(),map(),input(),and split() functions.
# Store it in a variable.
gvn_lst = list(map(float, input(
    'Enter some random List Elements separated by spaces = ').split()))
# Give the first number as user input using the float(input()) function
# and store it in a variable.
gvn_numb1 = float(input("Enter some random number = "))
# Apply math.trunc() function to the given first number to remove the decimal
# part and give only the integer part of the given number. (truncate) 
# Store it in another variable.
trnc_numb = math.trunc(gvn_numb1)
# Print the truncated value of the given first number.
print("The truncated value of the given first number ",
      gvn_numb1, " = ", trnc_numb)
# similarly do the same for the other number.
gvn_numb2 = float(input("Enter some random number = "))
trnc_numb2 = math.trunc(gvn_numb2)
print("The truncated value of the given second number ",
      gvn_numb2, " = ", trnc_numb2)
# Apply math.trunc() function to the given list element and print it.
print(
    "The truncated value of the given list element ", gvn_lst[1], " = ", math.trunc(gvn_lst[1]))

Output:

Enter some random List Elements separated by spaces = 3 45.66 20.01 54
Enter some random number = 80.432
The truncated value of the given first number 80.432 = 80
Enter some random number = 22.4
The truncated value of the given second number 22.4 = 22
The truncated value of the given list element 45.66 = 45
