Python Program for modf() Function

In the previous article, we have discussed Python Program for How To Use While Not
modf() Function in Python:

The modf() math function in Python is used to divide a given value into two arguments. Python modf() function takes a fractional part as the first argument and an integer value as the second argument.

Syntax:

math.modf(Number);

Parameters

Number: It could be a number or a valid numerical expression.

Return Value:

If the number argument is positive or negative, the modf() function returns Zero.
If the number argument is positive or negative decimal, the modf() function returns decimal values for the first argument and an integer value for the second.
If it is not a number, the modf() function throws a TypeError.

For example:

Let the number = 3.75

Then the modf() gives 0.75 as the first argument and 3.00 as the second argument.

Therefore , output = (0.75, 3.00)

Examples:

Example1:

Input:

Given Number = 4.75

Output:

The result after applying modf() function on above given number 4.75  =  (0.75, 4.0)

Example2:

Input:

Given Number = 15

Output:

The result after applying modf() function on above given number 15 = (0.0, 15.0)

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.modf() function to the given first number to divide the given value into arguments(fractional part as the first argument and an integer value as the second argument).
Store it in another variable.
Print the above result.
Similarly, do the same for the other number.
Apply math.modf() 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 = [7, 4.65, 6.5, 14, 10]
# Give the first number as static input and store it in another variable.
gvn_numb1 = 4.75
# Apply math.modf() function to the given first number to divide the given value
# into arguments(fractional part as the first argument and an integer value
# as the second argument).
# Store it in another variable.
fnl_rslt = math.modf(gvn_numb1)
print("The result after applying modf() function on above given first number",
      gvn_numb1, " = ", fnl_rslt)
# similarly do the same for the other number.
gvn_numb2 = 15
print("The result after applying modf() function on above given second number",
      gvn_numb2, " = ", math.modf(gvn_numb2))
# Apply math.modf() function to the given list element and print it.
print(
    "The result after applying modf() function on given list element gvnlst[1] = ", math.modf(gvn_lst[1]))

Output:

The result after applying modf() function on above given first number 4.75  =  (0.75, 4.0)
The result after applying modf() function on above given second number 15  =  (0.0, 15.0)
The result after applying modf() function on given list element gvnlst[1] =  (0.6500000000000004, 4.0)

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.modf() function to the given first number to divide the given value into arguments(fractional part as the first argument and an integer value as the second argument).
Store it in another variable.
Print the above result.
Similarly, do the same for the other number.
Apply math.modf() 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.modf() function to the given first number to divide the given value
# into arguments(fractional part as the first argument and an integer value
# as the second argument).
# Store it in another variable.
fnl_rslt = math.modf(gvn_numb1)
print("The result after applying modf() function on above given first number",
      gvn_numb1, " = ", fnl_rslt)
# similarly do the same for the other number.
gvn_numb2 = float(input("Enter some random number = "))
print("The result after applying modf() function on above given second number",
      gvn_numb2, " = ", math.modf(gvn_numb2))
# Apply math.modf() function to the given list element and print it.
print(
    "The result after applying modf() function on given list element gvnlst[3] = ", math.modf(gvn_lst[3]))

Output:

Enter some random List Elements separated by spaces = 12 13 14.674 30.238
Enter some random number = 32.49
The result after applying modf() function on above given first number 32.49 = (0.490000000000002, 32.0)
Enter some random number = 59.759
The result after applying modf() function on above given second number 59.759 = (0.7590000000000003, 59.0)
The result after applying modf() function on given list element gvnlst[3] = (0.23799999999999955, 30.0)
