Error at integer validation

[ManuSenpai]

Context

• node version: 8.6.0
• joi version: 13.2.0
• environment (node, browser): Chrome
• used with (hapi, standalone, ...): Standalone

What are you trying to achieve or the steps to reproduce ?

I'm trying to validate a possitive integer which length is between 10 and 15 characters

This is the code I am using

function validateNumber (value) {
return _.isNull(joi.validate(value, joi.string().required().min(10).max(15)).error) &&
_.isNull(joi.validate(value, joi.number().integer().min(0).required()).error);
}

Which result you had ?

I used as a value 999999999. (9 integers and a decimal point) and joi validates it as a 10 digit integer

What did you expect ?

I expected it to throw an error as it is not a digit. Given 999999999.9 as value throws an error correctly.

I'm pretty sure this is because of how Node.js handles decimal points:

> Number.isSafeInteger(1.)
true
> Number.isSafeInteger(1.0)
true
> Number.isSafeInteger(1.1)
false

Will be fixed in 14. Closing for now.
