” CSE 320程序 写作、 辅导programming、c/c++程序 辅导CSE 320 Fall 2020Computer Project #6Assignment OverviewThis assignment develops familiarity with the C programming language, the gcc compiler, integer operations, andfloating point representation.It is worth 40 points (4% of course grade) and must be completed no later than 11:59 PM on Thursday, 10/22.Assignment DeliverablesThe deliverables for this assignment are the following files:proj06.support.c the source code for your library moduleproj06.driver.c the source code for your driver moduleproj06.makefile the makefile which produces proj06Be sure to use the specified file names and to submit them for grading via the CSE handin system before theproject deadline.Assignment SpecificationsSome microprocessors do not have floating point hardware. Thus, floating point operations on those systemsmust be performed using software.1. You will develop a library module of C functions which operate on floating point values using only integeroperations. The library module will include the functions listed below:float get_infinity(); /* Return infinity */float get_nan(); /* Return not-a-number */float get_max_normal(); /* Return largest normal */float get_min_normal(); /* Return smallest normal */float get_max_denormal(); /* Return largest denormal */float get_min_denormal(); /* Return smallest denormal */int is_negative( float ); /* Test if argument is negative */int is_infinity( float ); /* Test if argument is infinity */int is_nan( float ); /* Test if argument is not-a-number */int is_zero( float ); /* Test if argument is zero */int is_denormal( float ); /* Test if argument is denormal */float negate( float ); /* Return negation of argument */float absolute( float ); /* Return absolute value of argument */The first six functions will return the specified single precision value (all will be positive). The return value fromfunction get_nan will have a fraction field were each of the bits is a 1.The next five functions will return 0 if the specified condition is false, and 1 if the condition is true.Functions negate and absolute will perform the appropriate operation on the argument and return the result.The function declarations (and some auxiliary declarations) are available on the CSE system as:/user/cse320/Projects/project06.support.hYour implementation of the library module will not use any floating point operations, with one exception: any ofthe functions may use the assignment operation to copy a floating point value from one variable to another.The functions in your library module will not call any C library functions (such as printf, scanf and isnan).2. You will develop a driver module to test your implementation of the library module. The driver module willconsist of function main and any additional helper functions which you choose to implement.Your driver module will not be an interactive program, where the user supplies input in response to prompts.Instead, your test cases will be included in the source code as literal constants.All output will be appropriately labeled.Assignment Notes1. The Harris and Harris text contains information about floating point representation and operations (particularlypages 256-259).2. The source code for the library module and the driver module must be in separate files. And, your source codefiles must be translated by gcc, which is a C compiler and accepts C source statements.3. You must supply a makefile (named proj06.makefile), and that makefile must produce an executable programnamed proj06.4. In order to work with a 32-bit item as both a floating point value and an integer value, you might consider usinga union. For example:#include stdio.hunion ieee_single{float frep;unsigned int irep;};int main(){union ieee_single num;num.frep = 1.5;printf( Real: %f Hex integer: %08x \n, num.frep, num.irep );}When compiled and executed, that program produces the following:Real: 1.500000 Hex integer: 3fc00000The memory location num can be referenced as an object of type float (using num.frep) and an object of typeunsigned int (using num.irep).如有需要，请加QQ：99515681 或邮箱：99515681@qq.com
