# Error de dominio (argumento de entrada está fuera del rango en el que se matemáticamente la operación definida, por ejemplo std::sqrt(-1), std::log(-1), o std::acos(2)). Si el bit se establece MATH_ERRNO, EDOM se asigna a errno. Si el bit se establece MATH_ERREXCEPT, FE_INVALID se eleva .
Original:
# Domain error (input argument is outside the range in which the operation is mathematically defined, e.g. std::sqrt(-1), std::log(-1), or std::acos(2)). If MATH_ERRNO bit is set, EDOM is assigned to errno. If MATH_ERREXCEPT bit is set, FE_INVALID is raised.

# Rango de error (el resultado matemático no puede ser representada como el objeto de tipo especificado, por ejemplo std::atanh(-1), std::log(0.0), std::lgamma(0.0) o). Si el bit se establece MATH_ERRNO, ERANGE se asigna a errno. Si el bit se establece MATH_ERREXCEPT, FE_DIVBYZERO o FE_OVERFLOW se eleva .
Original:
# Range error (the mathematical result cannot be represented as the object of specified type, e.g. std::atanh(-1), std::log(0.0), or std::lgamma(0.0)). If MATH_ERRNO bit is set, ERANGE is assigned to errno. If MATH_ERREXCEPT bit is set, FE_DIVBYZERO or FE_OVERFLOW is raised.

Overflow # (el resultado matemático es finito, pero demasiado grande para ser representados sin error de redondeo extrema, por ejemplo, funciones como std::exp con argumentos suficientemente grandes). Si el bit se establece MATH_ERRNO, ERANGE se asigna a errno. Si el bit se establece MATH_ERREXCEPT, FE_OVERFLOW se eleva .
Original:
# Overflow (the mathematical result is finite, but too big to be represented without extreme roundoff error, e.g. functions such as std::exp with sufficiently large arguments). If MATH_ERRNO bit is set, ERANGE is assigned to errno. If MATH_ERREXCEPT bit is set, FE_OVERFLOW is raised.

# Subdesbordamiento (el resultado matemático no es cero, pero demasiado pequeño para ser representado sin error de redondeo extrema, por ejemplo, el resultado es inferior a la normal, como en std::sin(subnormal) o para muchas otras funciones con argumentos subnormales). Si el bit está establecido MATH_ERRNO, ERANGE puede ser asignado a errno. Si el bit se establece MATH_ERREXCEPT, FE_UNDERFLOW puede elevarse .
Original:
# Underflow (the mathematical result is non-zero, but too small to be represented without extreme roundoff error, e.g. the result is subnormal, as in std::sin(subnormal) or for many other functions with subnormal arguments). If MATH_ERRNO bit is set, ERANGE may be assigned to errno. If MATH_ERREXCEPT bit is set, FE_UNDERFLOW may be raised.
