need to add '%' symbol to my float type dataframe in python - Stack Overflow
Hence have tagged both python and pyspark. ... You can not add a % to the float and keep it as a float. You either have to send each as strings (format the number as a string with the '%'), ... Or send as is. You could also just send as a float where 1.0 = 100%, .1 = 10% etc, however that is still not adding the % symbol... More on stackoverflow.com
What does the float function do?
A float is a floating point number which is a computers representation of a real number (where an integer can only hold whole numbers, real numbers can also be decimals etc). All the float function does is convert what you give it into a floating point number. e.g float(10) will return 10.0 float("10") will also return 10.0 float("10.5") will return 10.5 More on reddit.com

Why is the power operator much slower than multiplication in Python?
The way most computers compute a power, special cases (NaN, inf, ...) aside, is to do 2^(y*log2(x)) for x^y. This takes 12 x86-64 instructions, although two of them are likely to happen simultaneously. In contrast, x*x is a single x86 instruction. So, for y=2, x*x should be about ten times faster. Python (or any other language) could specialize power to be x*x N times when N <= 10 or so, but the switch statement it takes to specialize the cases isn't free. And the accumulation of floating point errors is not the same between the two. Optimizing pow to a sequence of multiplies is usually done by compilers, which look if you did pow(x,CONSTANT), and decide what to do depending on CONSTANT. That way it is done one time instead of N times at runtime. Python doesn't really have a compiler, so pow is slow for small y, because it would be slower for big y to optimize it for the small ys. Numpy does optimize x**2 to x*x for you, but does not optimize the other powers smaller than ten (actually, I forget if three is also a special optimized case but I know four isn't.)

Therefore, floating-point arithmetic can lead to precision issues and unexpected behavior. For example, checking for equality or summing up large amounts of data can be dangerous. ... sum = 0.1 + 0.2 print(sum) # Often outputs: 0.30000000000000004 print(sum == 0.3) # Often outputs: False · For high-precision needs, particularly in financial applications, Python's decimal module provides operations for decimal arithmetic.

July 10, 2025 - Use string replacement methods (remove commas, replace decimal separators) or Python’s locale module to convert European-style numbers like "1.234,56" to standard format. float(None) raises a TypeError, not ValueError; so explicitly check for None values before attempting conversion to avoid different exception types. Remove unwanted characters like currency symbols, thousands separators, and whitespace using string methods like .strip() and .replace() before calling float().
