) noexcept

Scale one unsigned magnitude exactly without overflowing intermediate products.

Returns: true only when the rational result is integral and fits limit.

Parameters

magnitude

std::uint64_t

Input magnitude.

numerator_a

std::uint64_t

First numerator factor.

numerator_b

std::uint64_t

Second numerator factor.

denominator_a

std::uint64_t

First denominator factor.

denominator_b

std::uint64_t

Second denominator factor.

limit

std::uint64_t

Inclusive output limit.

output

std::uint64_t &

Receives the scaled magnitude on success.
