This data type represents integers. The following table shows various keywords used to declare integer data types:
Keyword |
Types |
Details |
int |
Signed integer |
int8 to int256, which means that keywords are available from int8 up to int256 in increments of 8, for example, int8, int16, int24. |
uint |
Unsigned integer |
uint8, uint16, ... to uint256, unsigned integer from 8 bits to 256 bits. The usage is dependent on the requirements that how many bits are required to be stored in the variable. |
For example, in this code, note that uint is an alias for uint256:
uint256 x; uint y; uint256 z;
These types can also be declared with the constant keyword, which means that no storage slot will be reserved by the compiler ...
