- 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
- 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
- Should I use double or float? - Stack Overflow
1 The main difference between float and double is precision Wikipedia has more info about Single precision (float) and Double precision
- How are floating point numbers stored in memory? - Stack Overflow
To understand how they are stored, you must first understand what they are and what kind of values they are intended to handle Unlike integers, a floating-point value is intended to represent extremely small values as well as extremely large For normal 32-bit floating-point values, this corresponds to values in the range from 1 175494351 * 10^-38 to 3 40282347 * 10^+38 Clearly, using only
- 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
- What are the actual min max values for float and double (C++)
Float's precision allows it to store a value of up to 9 digits (7 real digits, +2 from decimal to binary conversion) Double, like the name suggests can store twice as much precision as a float
- 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
