二进制浮点运算，用51汇编语言编写的，适合于51汇编语言的学习者-binary floating-point operations, and 51 written in assembly language, suitable for 51 assembly language learners

本设计是用32位的并行全加器的,可以实现浮点运算!-The design is a parallel 32-bit full adder, and floating-point operations can be achieved!

在c下实现了PL0编译器的实现，并且扩充了write和for功能，增加了数组和浮点数的定义，功能更加强大(Under C, the implementation of PL0 compiler is realized, and the functions of write and for are extended. The definition of array and floating point number is added, and the function is more powerf
