std::feraiseexcept - cppreference.com (original) (raw)
| | | | | --------------------------------- | | ------------- | | int feraiseexcept( int excepts ); | | (since C++11) |
Attempts to raise all floating point exceptions listed in excepts (a bitwise OR of the floating point exception macros). If one of the exceptions is FE_OVERFLOW or FE_UNDERFLOW, this function may additionally raise FE_INEXACT. The order in which the exceptions are raised is unspecified, except that FE_OVERFLOW and FE_UNDERFLOW are always raised before FE_INEXACT.
[edit] Parameters
| excepts | - | bitmask listing the exception flags to raise |
|---|
[edit] Return value
0 if all listed exceptions were raised, non-zero value otherwise.
[edit] Example
Output:
Raising divbyzero and underflow simultaneously succeeds and results in division by zero underflow
