How do you cast long to int?

long l = 42; int i = (int) l; However, a long can hold more information than an int , so it's not possible to perfectly convert from long to int , in the general case. If the long holds a number less than or equal to Integer. MAX_VALUE you can convert it by casting without losing any information.

Considering this, what happens when you cast long to int?

When one needs to force a Long into an int there is potential for integer overflow because the numeric value of the Long may have a greater magnitude than the int can accurately represent. If one is told that a given Long will never be larger than what an int can hold, the static method Math.

One may also ask, how do you cast long to string? There are three main ways to convert a long value to String in Java e.g. by using Long. toString(long value) method, by using String. valueOf(long) and by concatenating with an empty String. You can use any of these method to convert a long data type into String object.

Also question is, how do you convert long to int in Python?

Number Type Conversion

  1. Type int(x) to convert x to a plain integer.
  2. Type long(x) to convert x to a long integer.
  3. Type float(x) to convert x to a floating-point number.
  4. Type complex(x) to convert x to a complex number with real part x and imaginary part zero.

Can we compare long and int in Java?

2 Answers. Yes, that's fine. The int will be implicitly converted to a long , which can always be done without any loss of information. You can compare long and int directly however this is not recommended.
