“よく生きたねと褒めてもらえるよう”娘がつづる15年目の思い
Convert the XYZ values to Lab using the following formulas. Note that we typically use the 2° standard observer for this conversion, as it is the most commonly used for color matching.\[X_n = 0.95047 \quad (\text{reference white point for D65 illuminant})\]\[Y_n = 1.00000\]\[Z_n = 1.08883\]\[f(t) = \begin{cases}t^{\frac{1}{3}} & \text{if } t 0.008856 \\7.787 \cdot t + \frac{16}{116} & \text{otherwise}\end{cases}\]\[L^* = 116 \cdot f\left(\frac{Y}{Y_n}\right) – 16\]\[a^* = 500 \cdot \left( f\left(\frac{X}{X_n}\right) – f\left(\frac{Y}{Y_n}\right) \right)\]\[b^* = 200 \cdot \left( f\left(\frac{Y}{Y_n}\right) – f\left(\frac{Z}{Z_n}\right) \right)\]，这一点在新收录的资料中也有详细论述

No exceptions with stack unwinding. Error handling uses Result with explicit propagation via ?. Errors are values, not control flow.
As of March. 10, the Garmin Forerunner 965 is on sale for $399.99 at Amazon, which is a solid $200 discount from its list price of $599.99. Since it marks a new low price for the smartwatch, the timing couldn't be better to make a move on it.，更多细节参见PDF资料
