To get number without decimal places in Python, you can use Python built-in functions like int(), round(), or math.trunc() function. Read the following article for more details.
Get number without decimal places in Python
Use the int() function
Syntax:
int(value, base)
Parameters:
- value: The number or string you want to convert to an integer.
- base: Number represents the number format. The default is 10.
The int() function returns:
- An integer from the number or string you pass in.
- Returns 0 if the parameter is left blank.
Example:
- Declare a variable containing decimals.
- Using the int() function, it will truncate floating numbers to zero returning an integer representing the number without decimals.
floatVar = 1.2
# Use the int() function to take an integer
intVar = int(floatVar)
print('The Integer is:', intVar)Output:
The Integer is: 1Use the round() function
Syntax:
round(number[, ndigits])
Parameters:
- number: Number you want to round.
- ndigits: The number of digits you want after the decimal point.
Return value from the round() function:
- If there are no ndigits, the function returns the nearest integer.
- If two arguments are provided, the function returns a number with ndigits decimal places after the decimal point.
Example:
- Declare a variable containing decimals.
- The round() function will round a number up or down to an integer.
floatVar = 1.2
# Use the round() function to take an integer
intVar = round(floatVar)
print('The Integer is:', intVar)Output:
The Integer is: 1Separate the integer part and the decimal part
I can separate integer and decimal parts using split(), int() and list comprehensions.
Example:
- Separate the integer part and the decimal part.
- Then run them through the int() function to become an integer.
- Note: Float has no split attribute, so you need to initialize a string.
numberStr = '1.2'
# Separate the integer part and the decimal part
integerPart , decimalPart = [int(i) for i in numberStr.split('.')]
print('The integer part is:', integerPart)
print('The decima part is:', decimalPart)Output:
The integer part is: 1
The decimal part is: 2Use the math.trunc function
Syntax:
math.trunc(value)
Parameters:
- value: Real numbers need to remove the decimal part.
The math.trunc function returns an integer (decimals will be removed).
Example:
- Declare a variable containing decimals.
- Using the math.trunc() function will truncate floating numbers to zero returning an integer representing the number without decimals.
import math
floatVar = 1.2
# Use the math.trunc() function to take an integer
intVar = math.trunc(floatVar)
print('The Integer is:', intVar)Output:
The Integer is: 1Summary
