r/learnpython on Reddit: how to limit or round a float to only two decimals without rounding up
March 8, 2024 -
Hello,
Does anyone know how to limit or round a float to only two decimals without rounding up?
for example,
if the number is 3.149, then I want the output to be 3.14. If the number is 3.0, then the output must be 3.00
thank you

How to get float to two decimal places without rounding off.
Using only math, I believe you can do this: >>> f = 8.225 >>> f - f % 0.01 8.22 Using strings you can do something like this: >>> float(str(f)[:4]) 8.22 Some more examples of the first one just for fun: >>> r = lambda f: f - f % 0.01 >>> r(2.368) 2.36 >>> r(2.36888888) 2.36 >>> r(2.323) 2.32 >>> r(2.326) 2.32 Doesn't work with a single decimal, but works with 2 or more: >>> r = lambda f,p: f - f % p >>> r(2.356366,0.1) 2.3000000000000003 >>> r(2.356366,0.01) 2.35 >>> r(2.356366,0.001) 2.356 >>> r(2.356366,0.0001) 2.3563 >>> r(2.356366,0.00001) 2.35636 More on reddit.com

June 10, 2016How to truncate a float?
It's worth keeping in mind that the internal representation of floating point numbers in all the main programming languages including Python is not decimal but binary. This means that if you use string processing to set the number of decimal places then convert it back to a float, you'll lose the decimal precision anyway. e.g.: >>> a = float("0.1") >>> b = float("0.2") >>> a + b 0.30000000000000004 As has already been pointed out, you normally set the precision when converting to a string for displaying the result, so it's best to use the format() function or f-strings for output. If for some reason, you wish to maintain exact base-10 decimal precision throughout the calculations, because you're writing a finance program or something, then it's worth learning about the features of Python's decimal library.

Truncate numbers to decimal places in Python • TradingCode
The function then first multiplies that value with 100 (102). math.trunc() then truncates 1234.56 to a whole number. We then divide with 100 to get the result in 2 decimal places: 12.34.

You can use the round function, which takes as its first argument the number and the second argument is the precision after the decimal point.
In your case, it would be:
answer = str(round(answer, 2))

r/learnpython on Reddit: How to truncate a float?
July 1, 2022 -
I have a case where I need to truncate a float to the first decimal place. Very important - truncate, not round.
I wrote this function
def trunc(num : float, precision :int = 1):
return float(str(num)[0:precision+2])
which works most of the time, but if the number is particularly small, str(num) will return the scientific notation. So str(0.000094) returns 9.4e-05 which in turn means that str(0.000094)[0:3] returns 9.4.
For now I can np.trunc(num*10)/10 but I'm wondering if there's a better way.

One-liner function to print percentage:
k - the numerator
n - the denominator
'%.2f' - means you want a precision of 2 decimal places
*100 - turns the number from a decimal to a percentage
percentage = lambda k, n: '%.2f' % (k/n*100)
- equivalent to-
def percentage(k,n):
return '%.2f' % (k/n*100)
percentage(1,3)
output -> '33.33'
