DVF number functions

Number functions are used in a data validation function.

Use number functions in Data Validation Functions to validate attributes that are composed of numeric characters.

Table 1. Number Functions
Function	Description	Sample
`range`	The validation function checks that the attribute value is between the given date range. If the validation is met, then the appropriate validation message is displayed.	`range(attributes.Age.value,22,60)`
`equals`	The validation function checks that the attribute value exactly matches the given static number. If the validation is met, then the appropriate validation message is displayed. This function supports the NOT conditional operator.	`equals(attributes.Age.value,'16')`
`gt`	The validation function checks that the attribute value is greater than the given static number. If the validation is met, then the appropriate validation message is displayed. This function supports the NOT conditional operator.	`gt(attributes.Age.value,'20')`
`gte`	The validation function checks that the attribute value is greater than and equal to the given static number. If the validation is met then the appropriate validation message is displayed. This function supports the NOT conditional operator.	`gte(attributes.Age.value,'20')`
`lt`	The validation function checks that the attribute value is lesser than the given static number. If the validation is met, then the appropriate validation message is displayed. This function supports the NOT conditional operator.	`lt(attributes.Age.value,'20')`
`lte`	The validation function checks that the attribute value is lesser than or equal to the given static number. If the validation is met, then the appropriate validation message is displayed. This function supports the NOT conditional operator.	`lte(attributes.Age.value,'20')`
`exists`	The validation function checks that the given attribute value exists. If the validation is met, then the appropriate validation message is displayed.	`exists(attributes.Age.value)`
`missing`	The validation function checks that the given attribute value is missing. If the validation is met, then the appropriate validation message is displayed.	`missing(attributes.Age.value)`
