Input for type 'number' divisibleBy issue (2.99 not divisible by 0.01) #114

Description

@romaleev

Issue occurs with the following source for number=2.99 and divisibleBy=0.01, for other numbers works fine so far:
revalidator.validate({num: 2.99}, { properties: {num: {type: 'number', exclusiveMinimum: 0.98, exclusiveMaximum: 10, divisibleBy: 0.01, required: true, allowEmpty: false, messages: { allowEmpty: ' empty', exclusiveMinimum: ' > 0.98', exclusiveMaximum: ' < 10' } } } })

After investigation I found that an issue happens here

        case 'number':
          ...
          constrain('divisibleBy', value, function (a, e) {
            var multiplier = Math.max((a - Math.floor(a)).toString().length - 2, (e - Math.floor(e)).toString().length - 2);
            multiplier = multiplier > 0 ? Math.pow(10, multiplier) : 1;
            console.log(555, (a * multiplier), (e * multiplier))
            return (a * multiplier) % (e * multiplier) === 0 //<-----
            //for num === 3.99: 
          });
          break;

For 3.99 works fine:
(a * multiplier) // 3.99*10000000000000000 === 39900000000000000 /*divisible by*/ (e * multiplier) === 100000000000000

But for 2.99 - an error:
(a * multiplier) // 2.99*10000000000000000 === 29900000000000004 //<---!!! /*not divisible by*/ (e * multiplier) === 100000000000000

I'm using the latest Chrome 51.0.2704.103 (64-bit)
