but the string produced by VISIBLE didn't seem to be

HOW IZ I hex_to_char YR hex_string

OBTW This is a hack I found for converting hexadecimal strings

into their unicode character equivalents. Instead of using

|
the ":" character directly, we escape it and get it using its
|
||||||
|
unicode hex value (3A). This allows us to assemble the string
|

|
with our inserted hex value without errors.

Approximation Method as adapted in C at this website (#11):

OBTW Forcing a comparison between the accuracy and a number
|
||||||
|
which is so big that its precision is larger than the
|
||||||
|
accuracy causes an infinite loop to occur. For this
|

reason we have to set any number larger than 2^20 to

a value below it.

positions in a compressed and quickly accessed

manner. Unfortunately for us, bit operations

in LOLCODE were too slow for this to be a tenable
