Transform your float to hexadecimals and viceversa!
Add this line to your application's Gemfile:
And then execute:
Or install it yourself as:
$ gem install hex_values
require the gem:
And then transform any float to a hexadecimal:
234.25.to_hex # => "EA.4"
Or transform any hexadecimal to the corresponding float:
"EA.4".to_float # => 234.25
To be more precise, when you transoform a Float (or a Fixnum) to an hexadecimal, you get a Hexadecimal object. This object is a representation of the Hexadecimal value, and you can operate on this object:
hexa = 234.25.to_hex result = hexa + 234.25 result.to_s # => "1D4.8"
also you can operate over a Float (or a Fixnum) using an Hexadecimal value.
hexa = 234.25.to_hex result = 234.25 + hexa # I know, this is obvious...but is better to explain that works. result.to_s # => "1D4.8"
So far, the operations availables are:
- plus (+)
- minus (-)
- multiply (*)
- division (/)
- Power (**)
From float to Hex
The "to_hex" method allows a precision parameter to set the maximum number of decimals to calculate (default 14).
Bear in mind that the larger the number, the larger the amount of time used to get the number:
1875.37.to_hex(50) # => 753.5EB851EB851EB851EB851EB851EB851EB851EB851EB851EB85
