Summary
Jason highlights the often overlooked std::nextafter function from the C++ standard library, which returns the next representable floating-point value in a specified direction. This function solves the challenge of incrementing or decrementing a floating-point value by the smallest possible amount, which can be difficult to calculate manually due to the complexities of IEEE 754 representation. The episode demonstrates how std::nextafter can be used to find the next value toward zero or toward infinity.
