Floating Point Error Stack Underflow

The concepts introduced are reinforced with numerous examples and review exercises. Yes No Additional feedback? 1500 characters remaining Submit Skip this Thank you! Usually if the result of an operation cannot be represented in the given type (like in your example, the number 32768 on a 16-bit signed integer) the behaviour is undefined. –R.

I have searched but I can't seem to seem to find the solution. if it is a dos version then i have faced this problem before and the workaround is to include math.h and before ur processing initialize a dummy float variable, this will Any better way to determine source of light by analyzing the electromagnectic spectrum of the light How should I interpret "English is poor" review when I used a language check service Operations that overflow return an unspecified value whose magnitude is no greater than the smallest normalized positive number.

Floating-point underflow is not undefined behavior. share|improve this answer edited Jul 12 '13 at 11:33 answered Jul 12 '13 at 9:13 Pascal Cuoq 58.5k5101194 are there any other operations that may cause underflow? –WildThing Jul The time now is 05:24 PM.

More importantly, >HOW DO I STOP IT FROM HAPPENING!?!?! Search: Reference FE_UNDERFLOW macro FE_UNDERFLOW intUnderflow range error exception This macro expands to a value of type int that identifies the floating-point exception raised on underflow range errors. Note that “FPU exceptions” have nothing in common with C++ exceptions except the name. The book is suitable for use during courses on Microprocessors, Assembly language programming, and Computer Organization in order to understand the execution model of processors.

In the default mode, exact results never underflow.

NoteThe -fp-stack-check (Linux* and Mac OS* X) and the /Qfp-stack-check (Windows*) option causes significant code generation after every function/subroutine call to ensure that the floating-point stack is maintained in the correct

Still that underflow error. Float can handle numbers +or-3.4E-38 to +or-3.4E38 and Double can >handle numbers +or-1.7E-308 to +or-1.7E308. By contrast, the result of -2147483648-1 is -2147483649 which doesn't fit on a signed 32-bit int and therefore overflows/underflows. –R.
