Split whole number into float numbers Question: Goal: split 100 into 5 random 2 decimal place numbers. So far, I can simulate any number of divisions. However, these are only integers and are "balanced", in that they are the same or close in values to each other. So, the output is always the same. Code: …
AWS CDK Number Parameter as Integer Question: I’m using the AWS CDK and I’m struggling with the number parameter. The documentation says that numbers can be either an int or a float. Here’s how a number parameter is setup in the code: number_parameter = CfnParameter(self, "number_parameter", type="Number", description="Number Parameter") And here’s how I’m accessing the …
How to perform approximate structural pattern matching for floats and complex Question: I’ve read about and understand floating point round-off issues such as: >>> sum([0.1] * 10) == 1.0 False >>> 1.1 + 2.2 == 3.3 False >>> sin(radians(45)) == sqrt(2) / 2 False I also know how to work around these issues with math.isclose() …
Python large numbers (float and integer) Question: I am trying to understand the following calculation results. Out[1], Out[2] and Out[3] seem to be related to the limit on precision of floats, and Out[4] may be due to the fact that there is no limit on digits of int. Correct? I wonder if someone can explain …
How to read/write float values from a binary file in python, if the file was created with C Question: I want to read/write C float values from a binary file if it was created in C? The file was created like this: #include <stdio.h> int main() { const int NUMBEROFTESTELEMENTS = 10; /* Create the …
What is wrong with my implementation of numerical integration? Question: I think similar questions have answered here and here. I am also having similar problems with a code that performs the trapezoidal and simpson’s 1by3 rule. I have ran the code on a desktop which runs fine, but using a different machine, the code fails. …
Sympy check if a number is natural Question: If I some random number, how do I check if it’s an integer (∈ ℕ)? >>> from sympy.core.numbers import Float >>> Float(2) 2.00000000000000 >>> Float(2).is_integer False # what ?? I’ve found a simple workaround but I feel It’s some kind of a hack: >>> Float(2) % 1 …
Why does “np.inf // 2” result in NaN and not infinity? Question: I’m slightly disappointed that np.inf // 2 evaluates to np.nan and not to np.inf, as is the case for normal division. Is there a reason I’m missing why nan is a better choice than inf? Asked By: Aguy || Source Answers: I’m going …
Round decimal – If 1 then no decimal, if 0.01 then 2 decimal Question: How can i truncate not with casual number like 1, 2, 3 but directly with decimal syntax? For example: I have 4 and decimal to 1 so truncate to 4. I have 1.5 and decimal to 1 so truncate to 1. …
Truncate f-string float without rounding Question: I want to print a very very close-to-one float, truncating it to 2 decimal places without rounding, preferably with the least amount of code possible. a = 0.99999999999 print(f'{a:0.2f}’) Expected: 0.99 Actual: 1.00 Asked By: Michael Bianconi || Source Answers: I don’t think you need f-strings or math functions, …
