Feature request: Validate leading zero for numericality

[mondwan]

Goal:

• Expect "010" to be false in numericality validator

Description:

It will be great if there is an option like noLeadingZero in numericality.

Why

• Value from HTML5 number box is string
• The coercion of + will force "010" to be 10

Facts above make 010 to be a valid number which it should not be in reality in my opinion.

JS:

var c = {
    "numericality": {
    "greaterThanOrEqualTo":1,
    "lessThanOrEqualTo":100,
    "message":"<id> from 1 to 100",
  },
  "presence": true,
};

// Expect to be false, but get true
console.log(
    'validation result ',
    validate.single('010', c)
);

// No problem
console.log(
    'validation result ',
    validate.single('10', c)
);

Agreed, though I think the option should be called strict instead.

Please make this an option, I would like cases where it is the current behavior.

This option is optional by default

By the way, option has been renamed to strict as requested in the pull request. However, I am not sure how to deal with floating point number. Should I allow all trailing zero if that is a float?

If yes, I can simply add a check and bypass this checking.
