The Lang and Float Libraries
The Lang and Float Libraries are similar in that both contain several functions designed to perform various types of arithmetic operations. The main differences between these libraries are as follows:
The Lang functions calculate numbers without decimals (integer numbers).
The Float functions calculate numbers with decimals (floating-point numbers).
Working with arithmetic calculations usually requires a significant amount of processing power from the device performing the operations. Because of that, the functions within these libraries are not frequently used.
