hex_text

include std/convert.e 
default namespace is convert 
public function hex_text(sequence text) 

Converts a text representation of a hexadecimal number to an atom.

Parameters:

1. text : the text to convert.

Returns:

An atom, the numeric equivalent to text

Comments:

• The text can optionally begin with '#' which is ignored.
• The text can have any number of underscores, all of which are ignored.
• The text can have one leading '-', indicating a negative number.
• The text can have any number of underscores, all of which are ignored.
• Any other characters in the text stops the parsing and returns the value thus far.

Example 1:

include std/console.e -- for convert function 
include std/convert.e -- for display function 
 
atom h1 = hex_text("-#3_4FA.00E_1BD") 
? h1 
display("H1 is:[]",h1) -- note the difference in significant digits using ? vs display() 
atom h2 = hex_text("DEAD_BEEF") 
? h2 
display("H2 is:[]",h2) 
 

Results:

-13562.00344 
H1 is:-13562.0034444928 
3735928559 
H2 is:3735928559
