Javascript to force decimals in 0.25 steps

I have a few input values on a form that must be in 0.25 steps, how do I force this ? alternatively how do I automatically enter the correct vales as the user types and disallow any other values ie: as the firstnumber is typed (say 3) then .00 is added, then as the decimal point and the first decimal value is entered which must be either 0, 2, 5 or 7 then the appropriate second decimal is added which would be 0 or 5 as appropriate. I guess I will need an alert for any other values that might be entered in error?

I have googled and there are plenty of solutions to round to the nearest decimal but not to actually force 0.25 steps
I am sorry, I have absolutely no idea where to startSmilie

NAME
Test::BDD::Cucumber::StepFile - Functions for creating and loading Step Definitions VERSION
version 0.11 DESCRIPTION
Provides the Given/When/Then functions, and a method for loading Step Definition files and returning the steps. SYNOPSIS
Defining steps: #!perl use strict; use warnings; use Test::More; use Test::BDD::Cucumber::StepFile; use Method::Signatures; # Allows short-hand func method Given 'something', func ($c) { print "YEAH!" } When qr/smooooth (d+)/, func ($c) { print "YEEEHAH $1" } Then qr/something (else)/, func ($c) { print "Meh $1" } Step qr/die now/, func ($c) { die "now" } Loading steps, in a different file: use Test::BDD::Cucumber::StepFile; my @steps = Test::BDD::Cucumber::StepFile->load('filename_steps.pl'); EXPORTED FUNCTIONS
Given When Then Step Accept a regular expression or string, and a coderef. Some cute tricks ensure that when you call the "load()" method on a file with these statements in, these are returned to it... load Loads a file containing step definitions, and returns a list of the steps defined in it, of the form: ( [ 'Given', qr/abc/, sub { etc } ], [ 'Step', 'asdf', sub { etc } ] ) AUTHOR
