/* Generally, the C standard guarantees that at program startup, "trapping or stopping (if supported) is disabled on all [floating-point] exceptions" (F.7.3/1 of the August 3, 1998 draft of C99), and that during program execution, "a programmer can safely assume default modes (or be unaware of them)" (7.6/2, footnote 161 of the August 3, 1998 draft of C99). Reportedly, on Windows there are printer drivers that switch on exceptions. To avoid problems, the SAL_MATH_FPEXCEPTIONS_OFF macro can be used to explicitly switch off exceptions (on Windows).
