comparision of 32 bit signed numbers

 Hello friends, I need help in comparision of 32 bit signed numbers. I am generating random signed numbers using some logic & when i am doing addition of two numbers i am getting maximum value 0X80000000. how to avoid this? Example:# Expand|Select|Wrap|Line Numbers use strict ;   my \$a; my \$b; my \$result;   \$range = 2**31; # 2^(n-1): n=32  \$min = -2**31; #lowest integer  \$val= int(rand(\$range)) + \$min;  print "\$val\n"     \$a = \$val;   \$b = \$val;   \$result = \$a+\$b;   In the above example, \$result will overflow i.e exceeds the range 0x8000000 after addition of two signed numbers, & am getting result as 0x8000000 only, in order to avoid this what i need to do? Thanks Raghavendra Oct 31 '08 #1

Thanks Raghavendra I dont know but its working fine for me val := -1149894656 result := -2299789312 Oct 31 '08 #2
 hey man i have just posted an example in order understand my question, if overflows what to do ? & if it in hexadecimal format how to compare with >0 or <0, i am getting the wrong result Oct 31 '08 #3
