Package Exports

is-positive-integer

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (is-positive-integer) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Ensure positive integer less than Number.MAX_SAFE_INTEGER https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number/MAX_SAFE_INTEGER

var isSafePositiveInteger = require('is-positive-integer').isSafePositiveInteger
// max safe integer doesn't exist in older engines
var MAX_SAFE_INTEGER = Number.MAX_SAFE_INTEGER || 9007199254740991

isSafePositiveInteger(MAX_SAFE_INTEGER) // true
isSafePositiveInteger(MAX_SAFE_INTEGER + 1) // false
isSafePositiveInteger(Number.MAX_VALUE) // false
// ...
