Summary
A minor package that provides the type aliases int
, long
, float
and double
for number types in TypeScript.
The types int
, float
and double
are aliases for number
, long
is an alias for bigInt
.
While the TypeScript compiler cannot enforce the associated number ranges (e.g., restricting int
to the 32 bit signed integer range),
these type aliases allow for a more precise notation of number types.
This serves documentation purposes and makes the code more readable.
For example, a variable that represents an index could be declared an int
,
while a variable used for computations could be declared a double
.
Also, this may simplify things if code should later be ported from TypeScript to some other language.
Usage Example
import { int, double } from "@kobayami/number-types";
function getElementAt<T>(array: T[], index: int): T {
return array[index];
}
function getDistance(velocity: double, time: double): double {
return velocity * time;
}
