#Ski Binding Release Value Calculator
Calculates the initial indicator value (z-value) according to ISO 11088 standard.
Installation
Add to your Gemfile: gem ski_binding_calculator
, run $ bundle install
.
Even though not version 1.x this gem is stable and fully tested. Productive use is possible but at your own risk.
The gem is not version 1.x because some features are missing. According to ISO 11088 there are beside the indicator release value also twist and forward lean tolerances. Those are missing and will be implemented one day.
Usage
You can give the calculator a hash with the following key value pairs:
key | value |
---|---|
weight | float, string |
height | float, string |
sole_length | float, string |
birthday_year | int, string |
birthday_month | int, string |
birthday_day | int, string |
type | string |
A key can be a string
or symbol
.
Measuring Units & Formats
The measuring units and formats of the attributes are as follows:
attribute | unit |
---|---|
weight | [kg] |
height | [cm] |
sole_length | [mm] |
birthday_year | [yyyy] |
birthday_month | [mm] |
birthday_day | [dd] |
type | ["Type1-", "Type1", "Type2", "Type3", "Type3+"] |
Example
Regarding the last two sections a hash could look like that:
{ :type => "Type2",
:weight => "70",
:height => "170",
:sole_length => "315",
:birthday_year => "1983",
:birthday_month => "01",
:birthday_day => "01" }
Codes
In ISO 11088 table B.1 are codes defined. We map the codes to digits as follows:
code | digit |
---|---|
A | 0 |
B | 1 |
C | 2 |
D | 3 |
E | 4 |
F | 5 |
G | 6 |
H | 7 |
I | 8 |
J | 9 |
K | 10 |
L | 11 |
M | 12 |
N | 13 |
O | 14 |
P | 15 |
The mappings allow us to use the codes as array indexes in the yaml files.
