 === The +validates_numericallity_of+ helper
 
-=== The +validates_presence_of+ helper
+This helper validates that your attributes have only numeric values. By default, it will match an optional sign followed by a integral or floating point number. Using the +:integer_only+ option set to true, you can specify that only integral numbers are allowed.
 
-=== The +validates_size_of+ helper
+If you use +:integer_only+ set to +true+, then it will use the +$$/\A[+\-]?\d+\Z/$$+ regular expression to validate the attribute's value. Otherwise, it will try to convert the value using +Kernel.Float+.
