`mp_units::utility::safe_int`¶

Wraps an integral type with overflow detection.

Synopsis¶

Declared in <mp-units/utility/safe_int.h>

template<
  /* implementation-defined */ T, OverflowPolicy EP = safe_int_throw_policy>
class safe_int;

Description¶

This class wraps any integral type and models all requirements for mp-units representation types (RealScalar, UnitMagnitudeScalable, etc.). Every arithmetic operation checks for overflow and delegates to the ErrorPolicy::on_overflow() handler on detection.
