- What is the difference between float and double? - Stack Overflow
I've read about the difference between double precision and single precision However, in most cases, float and double seem to be interchangeable, i e using one or the other does not seem to affec
- integer - What exactly is a float? - Stack Overflow
This is the reason why we call them "floating point numbers" - we allow the decimal point to "float" depending on how big the number that we want to write is Let's give an example in decimal notation Suppose that you are given 5 cells to write down a number: _ _ _ _ _ If you don't use decimal points, then you can represent numbers from 0 to
- Ranges of floating point datatype in C? - Stack Overflow
The values for the float data type come from having 32 bits in total to represent the number which are allocated like this: 1 bit: sign bit 8 bits: exponent p 23 bits: mantissa The exponent is stored as p + BIAS where the BIAS is 127, the mantissa has 23 bits and a 24th hidden bit that is assumed 1 This hidden bit is the most significant bit (MSB) of the mantissa and the exponent must be
- floating point - What range of numbers can be . . . - Stack Overflow
For a given IEEE-754 floating point number X, if 2^E <= abs(X) < 2^(E+1) then the distance from X to the next largest representable floating point number (epsilon) is: epsilon = 2^(E-52) % For a 64-bit float (double precision) epsilon = 2^(E-23) % For a 32-bit float (single precision) epsilon = 2^(E-10) % For a 16-bit float (half precision) The above equations allow us to compute the following

- Difference between (float *) *(float*) in C - Stack Overflow
casting to float * here is not meaningful, because the void * address is the same as the float * address and also the int * address, the difference would be when you do pointer arithmetic You are casting the int pointer to a float and dereferencing the resulting float pointer, although it will violate strict aliasing rules in c Copy
- What is the inclusive range of float and double in Java?
What is the inclusive range of float and double in Java? Why are you not recommended to use float or double for anything where precision is critical?
- 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
