- What is the difference between float and double? - Stack Overflow
As the name implies, a double has 2x the precision of float [1] In general a double has 15 decimal digits of precision, while float has 7 Here's how the number of digits are calculated: double has 52 mantissa bits + 1 hidden bit: log(2 53)÷log(10) = 15 95 digits float has 23 mantissa bits + 1 hidden bit: log(2 24)÷log(10) = 7 22 digits
- How to use % operator for float values in c - Stack Overflow
consider : int 32 bit and long long int of 64 bits Yes, %(modulo) operator isn't work with floats and double if you want to do the modulo operation on large number you can check long long int(64bits) might this help you
- Is there a way to define a float array in Python? - Stack Overflow
When you are doing physics simulations you should definitely use floats for everything 0 is an integer constant in Python, and thus np tile creates integer arrays; use 0 0 as the argument to np tile to do floating point arrays; or preferably use the np zeros(N) instead:
- c# - When to use a Float - Stack Overflow
Short answer: You only have to use a float when you know exactly what you're doing and why Long answer: floats (as opposed to doubles) aren't really used anymore outside 3D APIs as far as I know Floats and doubles have the same performance characteristics on modern CPUs, doubles are somewhat bigger and that's all If in doubt, just use double
- Difference between numeric, float and decimal in SQL Server
Decimal has a fixed precision while float has variable precision EDIT (failed to read entire question): Float(53) (aka real) is a double-precision (64-bit) floating point number in SQL Server Regular Float is a single-precision (32-bit) floating point number Double is a good combination of precision and simplicty for a lot of calculations
- Qual a forma correta de usar os tipos float, double e decimal?
float e double A diferença entre o float e o double é a precisão, ou seja, o quanto varia, o quanto consegue expressar um valor próximo do real, é o número de casas decimais que ele consegue suportar Esses tipos são chamados de ponto flutuante binários O float normalmente possui 32 bits para representar o expoente e a mantissa, além
- Why dividing two integers doesnt get a float? [duplicate]
This is because of implicit conversion The variables b, c, d are of float type But the operator sees two integers it has to divide and hence returns an integer in the result which gets implicitly converted to a float by the addition of a decimal point If you want float divisions, try making the two operands to the floats Like follows
- floating point - C: printf a float value - Stack Overflow
printf("%0k yf" float_variable_name) Here k is the total number of characters you want to get printed k = x + 1 + y (+ 1 for the dot) and float_variable_name is the float variable that you want to get printed Suppose you want to print x digits before the decimal point and y digits after it
