Select a cell and type this formula =A1-TRUNC(A1) (A1 is the cell you want to extract decimal value from) into the Formula Bar, and then press Enter key. Keep selecting the first result cell, and drag fill handle down to get all results. You can see the decimal values are extracted with sign as below screenshot shown.
Use str. format() with “{:. 2f}” as string and float as a number to display 2 decimal places in Python. Call print and it will display the float with 2 decimal places in the console.
The number before the decimal point is called the whole part or integral part, Whereas the number after the decimal point is called the fractional part. Example : 43 is a whole part and 012 is a fractional part.
5.55 % 1
Keep in mind this won't help you with floating point rounding problems. I.e., you may get:
0.550000000001
Or otherwise a little off the 0.55 you are expecting.
Use modf:
>>> import math
>>> frac, whole = math.modf(2.5)
>>> frac
0.5
>>> whole
2.0
What about:
a = 1.3927278749291
b = a - int(a)
b
>> 0.39272787492910011
Or, using numpy:
import numpy
a = 1.3927278749291
b = a - numpy.fix(a)
Using the decimal module from the standard library, you can retain the original precision and avoid floating point rounding issues:
>>> from decimal import Decimal
>>> Decimal('4.20') % 1
Decimal('0.20')
As kindall notes in the comments, you'll have to convert native floats to strings first.
An easy approach for you:
number_dec = str(number-int(number))[1:]
