FLOAT vs DOUBLE

Question

Cual es la diferencia entre estos tipos de variables

Answer 1

Their only difference is their storage capacity.
As I don't remember what their actual capacity is I'll give an example with an analogy.
Floats can hold up to say 5 digits like 0.54321
Doubles up to say 20 digits like 0.1234567890987654321
Aside this they also have a marginal impact on performance.
Using a data type that accurately describes the data you are using saves a little time in your program.
That applies for all data types not just doubles and floats.

Answer 2

la diferencias son
- El formato de cada uno dado por la ieee
- La mantisa ya que la del float es variable y la del double no
- El cero absoluto no existe en float
- Existe mayor precisión en double
- El número de bits 32 para float y 64 para doble

Answer 3

The differences are
- The format of each given by the ieee
- The mantisa since the float is variable and the double is not
- Absolute zero does not exist in float
- There may be precision in double
- The number of 32 bits for float and 64 for double

Answer 4

I hope this will help, although the TS asked in Spain.

Hth, sorry I don't speak Spain.

Answer 5

a double is bigger than a float. most likely the 2 types you will be using are doubles and ints so u don't need to worry bout it
