int class - dart:core library
An integer number.
The default implementation of int is 64-bit two's complement integers with operations that wrap to that range on overflow.
Note: When compiling to JavaScript, integers are restricted to values that can be represented exactly by double-precision floating point values. The available integer values include all integers between -2^53 and 2^53, and some integers with larger magnitude. That includes some integers larger than 2^63. The behavior of the operators and methods in the int class therefore sometimes differs between the Dart VM and Dart code compiled to JavaScript. For example, the bitwise operators truncate their operands to 32-bit integers when compiled to JavaScript.
Classes cannot extend, implement, or mix in int.

other.

modulus.

toRadixString(int radix) → String
-
Converts this int to a string representation in the given
radix.

precision significant digits.
inherited
-
toUnsigned(int width) → int
