Checks whether a safe_int equals a floating‐point value.

[[nodiscard]]
constexpr
bool
operator==(
    safe_int lhs,
    U rhs);

Checks whether a safe_int equals an integral scalar, comparing safely across signedness.

[[nodiscard]]
constexpr
bool
operator==(
    safe_int lhs,
    U rhs);

Checks whether two safe_int values wrap equal underlying values.

[[nodiscard]]
constexpr
bool
operator==(
    safe_int lhs,
    safe_int rhs) noexcept;

Return Value

  • true if the underlying values are equal

  • true if the wrapped value equals rhs

  • true if the wrapped values are equal

Note

The return value should not be discarded.
