• floating point precision in ruby on rails model validations

  - by Chris Allison

  Hello I am trying to validate a dollar amount using a regex: ^[0-9]+\.[0-9]{2}$ This works fine, but whenever a user submits the form and the dollar amount ends in 0(zero), ruby(or rails?) chops the 0 off. So 500.00 turns into 500.0 thus failing the regex validation. Is there any way to make ruby/rails keep the format entered by the user, regardless of trailing zeros?

The additional query: SELECT COUNT(1) AS `zend_paginator_row_count` FROM `content` The normal query: SELECT `content`.`id`, `content`.`name` FROM `content` LIMIT 2 PHP: $adapter = new Zend_Paginator_Adapter_DbSelect($table->select()->from($table, array('id', 'name'))); $paginator = new Zend_Paginator($adapter); Could I merge the two querys into one (for better performance)?
