Top Forums Web Development Javascript to force decimals in 0.25 steps Post 302918986 by jim mcnamara on Friday 26th of September 2014 01:38:13 PM

OK. javascript uses floating point arithmetic operations (as compiled from C code).

Floating point does not always represent some numbers precisely, especially after several operations, e.g., addition, multiplication, etc. see -

What Every Computer Scientist Should Know About Floating-Point Arithmetic

You can convert fp -> string then display. You can also use convert.log() with a %f format specifier if your version supports a %f format specifier.

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
