###Description:
The company you work for has just been awarded a contract to build a payment gateway. In order to help move things along, you have volunteered to create a function that will take a float and return the amount formatting in dollars and cents.
39.99 becomes $39.99
The rest of your team will make sure that the argument is santized before being passed to your function although you will need to account for adding trailing zeros if they are missing (though you won't have to worry about a dangling period).
Examples:
3 needs to become $3.00
3.1 needs to become $3.10

Reading: link
possible scale inputs:
"C" for Celsius
"F" for Fahrenheit
"K" for Kelvin
"R" for Rankine
"De" for Delisle
"N" for Newton
"Re" for Réaumur
"Ro" for Rømer
temp is a number, from_scale and to_scale are strings.
Examples:
convert_temp( 100, "C", "F") # => 212
convert_temp( 40, "Re", "C") # => 50
convert_temp( 60, "De", "F") # => 140
convert_temp(373.15, "K", "N") # => 33
convert_temp( 666, "K", "K") # => 666
