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

const schema = Joi.number();
const validation = schema.validate('9.4e-1');
console.log(`value: ${validation.value}, message: ${validation.error}`);

What was the result you got?

value: 0.94, message: ValidationError: "value" must be a safe number

What result did you expect?

value: 0.94, message: undefined

I beleive that the problem lies in number.js#42 when the division hits a double precision value problem, i.e. :
0.94 / Math.pow(10, -1) results in 9.399999999999999
