int | main (int argc, char *argv[]) |
This is a driver program to test the functions defined in flt32.h and implemented in flt32.c. The program takes one or more command line parameters and calls one of the methods, then prints the results. To see how to use the program, execute testFlt32
in a terminal window. This will print a usage statement defining how to run the program. The first parameter of the program is always a key defining which function to run. The options are:
A sample execution might be: testFlt32 abs -2.5
which prints
2.5
All values may be entered as signed floating point numbers. The argument to lm1
may be a floating point number or a hex value.
int main | ( | int | argc, |
char * | argv[] | ||
) |
Entry point of the program
argc | count of arguments, will always be at least 1 |
argv | array of parameters to program argv[0] is the name of the program, so additional parameters will begin at index 1. |
void printBinary | ( | int | value | ) |
Print a 32 bit binary representation of a value.
value | the value to be printed |
void printBinaryMSB | ( | int | value, |
int | msb | ||
) |
Print the binary representation of a value starting at the specified bit position. A separator is printed every 4 bits for easy reading.
value | the value to be printed |
msb | the bit position to begin printing (31 to 0) |
