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.


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


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


I hope this will help, although the TS asked in Spain. * Wikipedia # Float https://en.wikipedia.org/wiki/Single-precision_floating-point_format # Double https://en.wikipedia.org/wiki/Double-precision_floating-point_format * Quora https://www.quora.com/What-is-meant-by-single-precision-and-double-precision-in-floating-point-data-types * StackOverflow https://stackoverflow.com/questions/801117/whats-the-difference-between-a-single-precision-and-double-precision-floating-p * Floating point guide http://floating-point-gui.de/formats/fp/ Hth, sorry I don't speak Spain.


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
