- What is the difference between float and double? - Stack Overflow
With type float, on the other hand, alarming-looking issues with roundoff crop up all the time And the thing that's not necessarily different between type float and double is execution speed
- How to correctly and standardly compare floats? - Stack Overflow
Note that float can approximately represent the latter and still smaller values - it's just about 7 decimals of precision after the first nonzero digit! If you're going to use a fixed epsilon, you should really choose it according to the requirements of the particular piece of code where you use it
- Qual a forma correta de usar os tipos float, double e decimal?
float e double são mais rápidos, eficientes e econômicos do que os BigDecimal s do Java; não posso afirmar muito sobre o Decimal do C#, mas creio que para multiplicação seja muito mais leve Normalmente, nos processadores mais modernos, existe um núcleo de processamento de aritmética de ponto flutuante
- Why are floating point numbers inaccurate? - Stack Overflow
Why do some numbers lose accuracy when stored as floating point numbers? For example, the decimal number 9 2 can be expressed exactly as a ratio of two decimal integers (92 10), both of which can be
- Ranges of floating point datatype in C? - Stack Overflow
float has 24 significant binary digits - which depending on the number represented translates to 6-8 decimal digits of precision double has 53 significant binary digits, which is approximately 15 decimal digits Another answer of mine has further explanation if you're interested
- How many digits can float8, float16, float32, float64, and float128 . . .
Numpy's dtype documentation only shows quot;x bits exponent, y bits mantissa quot; for each float type, but I couldn't translate that to exactly how many digits before after the decimal point Is
- Unsupported operand type (s) for *: float and Decimal
I guess this force you to cast float into decimal if you want decimal result, and cast decimal into float if you don't care about the precision
- The real difference between float32 and float64 - Stack Overflow
I want to understand the actual difference between float16 and float32 in terms of the result precision For instance, NumPy allows you to choose the range of the datatype you want (np float16, np
