Rounding is performed according to the current rounding mode. Whenever necessary, internal computations are done with a higher precision. If there are two possibilities to do this, round to even. The following functions return true if the assignment would be successful, false otherwise. No rounding is done.
Assignments Let a be of type bigfloat .
If successful, i.e. no overflow occurs, the function returns false and assigns a to d . Otherwise it returns true and leaves the value of d unchanged. If successful, i.e. no overflow occurs, the function returns false and assigns a to i . Otherwise it returns true and leaves the value of i unchanged. If successful, i.e. no overflow occurs, the function returns false and assigns a to i .
