 +====== About ======
 +
 +The API is compatible with the LOLCODE Specification 1.2. The functions have to be used between the opening and closing program blocks. For example:
 +
 +<code>
 +HAI 1.2
 +
 +[... insert function ...]
 +
 +  I HAS A VAR ITZ 4
 +  VISIBLE SMOOSH "Factorial: " AN I IZ WAS_FAK YR VAR MKAY
 +  
 +KTHXBYE
 +</code>
 +
 +will print out the factorial of ''4'' provided that the ''WAS_FAK'' function is inserted into the placeholder (this is because functions in LOLCODE cannot live outside of the ''HAI''/''KTHXBYE'' code-blocks.
 +
 +====== Numerical Inequalities ======
 +
 +A set of functions that perform various numerical inequalities following LaTeX syntax: ''LT'' ($<$), ''LE'' ($\le$), ''GT'' ($>$) and ''GE'' ($\ge$).

 +
 +This is a Lehmer random number generator,
 +
 +$$

 +$$
 +
 +using the ZX Spectrum Fermat prime vectors where $g=75$ and $n=65537$.

 +IF U SAY SO
 +</code>
 +
 +The algorithm will generate numbers in the interval $[0,65537)$ (larger if a different Fermat prime is chosen for $g$). The function takes a parameter an upper bound ''NUMBER'' and can be called using:
 +
 +<code lolcode>
 +VISIBLE I IZ WAS_MESS YR 100 MKAY
 +</code>
 +
 +which will generate a random number in the interval $[0, 100)$.

 +The ''WAS_FIB'' function prints out the first ''ROUNDS'' number of Fibonacci numbers starting with the initialisation vectors (either ''0'' and ''1'' or ''1'' and ''1'') passed to the function as ''FIRST'' and ''SECOND''.
