Yesterday's posting "Arrows in function names: func:b64⇉hex() and func:bin┈⇢dec()"

http://www.ibm.com/developerworks/forums/thread.jspa?threadID=394421
 

demonstrated that arrows from Unicode "Arrows" range 2190-21FF as well as other Unicode characters can be part of function names.

 

The attached and described stylesheet povides useful conversion functions in addition to dp:radix-convert() (see func:bin⇉hex() for a nice XPath technique).
Here a conversion of type "...⇉..." preserves leading '0's,
while a conversion of type "...┈⇢..." does not preserve leading '0's (like dp:radix-convert() ).
 


b64 (base64), hex, bin (01-strings) and dec (number) can be converted by these function calls:

 

hex: dp:radix-convert(_,64,16)
hex: func:b64⇉hex(_)
dec: dp:radix-convert(_,64,10)
 
hex to
b64: dp:radix-convert(_,16,64)
b64: func:hex⇉b64(_)
bin: func:hex⇉bin(_)
dec: dp:radix-convert(_,16,10)
 
bin to
hex: func:bin⇉hex(_)
dec: func:bin┈⇢dec(_)
