Validating numeric data

Numeric data validators validate float values and int values and numeric strings. A PHP string is considered numeric if it can be interpreted as an int or a float^[1].

Validators:

1. SmallerThan is lower bound validator: the length of the input must be atleast a given limit.
2. GreaterThan is upper bound validator: the length of the input must be below a given limit.
3. Between validator: value must be between the lower and upper limits.

Predefined errormessage Template formatting parameters:

1. :value - the string representation of the validated $value
2. :type - the datatype of the validated $value
   1. :type = "boolean" - for boolean type
   2. :type = "integer" - for integer type
   3. :type = "float" - for float type
   4. :type = "string" - for string type
   5. :type = "array" - for array type
   6. :type = "object" - for object type
   7. :type = "resource" - for resource type
   8. :type = "resource (closed)" - for closed resource type
   9. :type = "NULL" - for nulls
   10. :type = "unknown type" - for unknown types
3. :strict-type - the strict datatype of the validated $value differs from :type
   1. any object corresponds to the name of the class get_class() results

The Between validator

The Between validator validates whether numeric input is between two numbers. This range is either inclusive or exclusive.

Validator specific predefined errormessage Template formatting parameters:

1. :min - the minumum allowed value of the validated $value
2. :max - the maximum allowed value of the validated $value

The SmallerThan validator

The SmallerThan validator validates whether a float or an int input is msaller than or equal to a treshold value.

Validator specific predefined errormessage Template formatting parameters:

1. :max - the maximum allowed value of the validated $value

The GreaterThan validator

The GreaterThan validator validates whether a float or an int input is greater than or equal to a treshold value.

Validator specific predefined errormessage Template formatting parameters:

1. :min - the minumum allowed value of the validated $value
