v1.0

Completely refactored the previous code, the new code uses syntax trees instead of strings for operations, runs about 200% faster (both compiled with gcc -O3 option), and resolves an issue where specific input could raise an array subscript out-of-bounds segment error.

v0.4.2

• The calculation speed has been improved.
• Fixed a problem that may lead to memory leakage.

ProjectLambda v0.4.0

• Fixed several significant bugs in v0.3.0.
• Separated the functions/variables defined with set instruction from those defined with def instruction, now you should call them with a ! symbol rather than & symbol.
• list, calc, del instructions are renamed to dir, cal and clr, a new instruction fmt (to format the input) is introduced.
• Results of cal and del instructions will be automatically saved in ! and & variable.

ProjectLambda v0.3.0

• Optimised the formatting of output when the result of the calc instruction involves a function.
• Modified the behaviour of the def instruction and added a set instruction.
• Optimised internal algorithms.
• The exit command has been removed. You can use Ctrl-Z plus Return (on windows) or Ctrl-D (on linux) to exit the program.

ProjectLambda v0.2.0

X64 versions for both linux and windows.
