systems............. Well mostly. –Samuraisoulification Nov 21 '10 at 7:38 | show 1 more comment up vote 21 down vote for (i>0; i--;) is probably wrong and should be for (; i>0; i--) Since a modulus is, in its basic sense, division with a remainder, something % 0 IS division by zero and as such, will trigger a SIGFPE being thrown. When no trap is installed for the underflow exception, underflow is signaled (via the underflow flag) only when both tininess and loss of accuracy have been detected.

Why not use double throughout? There is no function called fct() in math.h Also you are using pow() function on two uninitialized float variables.

Then the only time it will divide later is c= input%i So it should never divide by 0? –Samuraisoulification Nov 21 '10 at 7:29 If you look carefully at Yet another … How to round up a floating point value whilst storing it as an integer value?? 8 replies Hi all, Im currently doing an assignment where we have been Expand|Select|Wrap|Line Numbers /*thisismathematicalfunctionofEXPONENT*/ #include #include #include doubleexponent(floate) { floatx,i,f=20; floatg; for(i=1;i<=f;i++) { e=pow(x,i); g=e/(fct(i)); } return(e); } voidmain() { clrscr(); { doubleexponent(floate); floatx,y; printf("\ninsertnumberforexponent\t\t"); scanf("%d",&x); y=exponent(x); We support it for historical compatibility, but recommend that you do not use it in new programs.

When you compile, use the "-g" flag to gcc to enable debugging info. The exponent, sign and mantissa together make up the number.

version4 should tell whether a number is prime or not prime. So a for loop's increment/decrement happens at the end of the loop even though you write it at the top? –Samuraisoulification Nov 21 '10 at 7:35 Yes, thats the Pep boys battery check reliable? Fix the area in question.

By default the exception is simply noted in the floating-point status word, and the program continues as if nothing had happened. a bullet shot into a suspended block Removing elements from an array that are in another array How do computers remember where they store things? Other operations that might lead to a NaN - 0/0, infinity/infinity, 0*infinity etc.Divide By Zero is raised when an operation of finite operands gives an infinite result.

When a floating-point exception raises the SIGFPE signal, the process terminates and produces a core file if no signal-handler subroutine is present in the process.

Multiplication: 0 · ∞. Looks like a possible division by zero. You should not use floating point here at all, since you only need integer operations. The way you have it setup now, you're returning zero for every value in your ncr function.

Yes, the square root of a negative number makes sense in the context of complex numbers, but there is no way to represent it in computers. Division: 0/0 or ∞/∞. See Signal Handling, for how you can change the effect of the signal. Round toward -∞ carries positive overflows to the largest representable finite number and negative overflows to -∞.
