Package Exports
- prose_number
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 (prose_number) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

A number Utility. Make writing node easier, prettier and less error prone. Writes and reads more like prose.
Usage
const number_util= require('prose_number');
// For all of the methods:
// The 1st parameter is a number if it is not a number it throws a exception.
// See prose_isit for a method to determine if a var is a number.
// inclusive defaults to false, if set and not a boolean an error is thrown.
// Returns true if number is between min and max (inclusive depending on the value of that paramater).
// If both min and max are nil then error is thrown.
// If min or max are set to something other than nill or a number an error is thrown.
// If min is nil and max is not, returns true if number less than min (or equal depending on inclusive).
number_util.between(anumber, min, max, inclusive);
// Cast a non number into a number.
// This will return a value only for number or strings that can be converted to numbers.
// Input a number and a number is returned.
// Input a string like "10" and 10 is returned.
// Input a string like "10,000" and 10000 is returned.
// By default any non number values are striped from the string.
// So '10-*&^0' returns 100.
// You may change what characters are stripped by setting last argument with a regular expression.
// So cast("10,000", /[,]/g) will return 10000
number_util.cast(number, regex);
// The inverse of the above between method.
number_util.notBetween(number, min, max, inclusive)
// Returns true if number greater than min (or equal depending on inclusive).
number_util.greaterthan(number, min, inclusive)
// Returns true if number less than max (or equal depending on inclusive).
number_util.lessthan(number, max, inclusive)
// Returns true if the input number is zero or greater.
number_util.zeroPositive(number)
// Returns true if the input number is a positive number greater than zero but not zero.
number_util.nonzeroPositive(number)
// Returns true if the input number is zero or less than zero.
number_util.zeroNegative(number)
// Returns true if the input number is a negative number less than zero but not zero.
number_util.nonzeroNegative(number)
