Invalid error message when using ScalePrecisionValidator

System Details

Issue Description

When using the ScalePrecisionValadator to validate the scale and precision of a decimal type property, I am getting this error message when submitting any whole digit number that violates the precision length portion of the validation.

'Decimal Property' may not be more than 9 digits in total, with allowance for 2 decimals. 9 digits and 1 decimals were found.

Shouldn’t the dynamic portion stating, “1 decimals were found.” be 0 decimals found?

i.e ‘123456789’

   RuleFor(x => x.DecimalProperty)
                .SetValidator(new ScalePrecisionValidator(2, 9)).WithName("Decimal Property");

Can’t you use the IgnoreTrailingZeros option on the ScalePrecisionValidator?

var validator = new InlineValidator<Person>();
var scalePrecisionValidator = new ScalePrecisionValidator(2, 9);
scalePrecisionValidator.IgnoreTrailingZeros = true;
validator.RuleFor(x => x.Discount).SetValidator(scalePrecisionValidator);

That should make it ignore any trailing zeros in the value it is validating.

Setting the IgnoreTrailingZeros property to true is fixing this issue. Thanks!
