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.

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.
