CUPERTINO, CALIFORNIA Apple today announced a new family of displays engineered to pair beautifully with Mac and meet the needs of everyone, from everyday users to the world’s top pros. The new Studio Display features a 12MP Center Stage camera, now with improved image quality and support for Desk View; a studio-quality three-microphone array; and an immersive six-speaker sound system with Spatial Audio. It also now includes powerful Thunderbolt 5 connectivity, providing more downstream connectivity for high-speed accessories or daisy-chaining displays. The all-new Studio Display XDR takes the pro display experience to the next level. Its 27-inch 5K Retina XDR display features an advanced mini-LED backlight with over 2,000 local dimming zones, up to 1000 nits of SDR brightness, and 2000 nits of peak HDR brightness, in addition to a wider color gamut, so content jumps off the screen with breathtaking contrast, vibrancy, and accuracy. With its 120Hz refresh rate, Studio Display XDR is even more responsive to content in motion, and Adaptive Sync dynamically adjusts frame rates for content like video playback or graphically intense games. Studio Display XDR offers the same advanced camera and audio system as Studio Display, as well as Thunderbolt 5 connectivity to simplify pro workflow setups. The new Studio Display with a tilt-adjustable stand starts at $1,599, and Studio Display XDR with a tilt- and height-adjustable stand starts at $3,299. Both are available in standard or nano-texture glass options, and can be pre-ordered starting tomorrow, March 4, with availability beginning Wednesday, March 11.
Commutativity and associativity might sound the same, and indeed most commutative operations are also associative. But there are a few math operations that are only one or the other. Matrix multiplication, for example, is associative but not commutative Matrix multiplication - Wikipedia en.wikipedia.org/wiki/Matrix_multiplication#Non-commutativity . And surprisingly, floating point arithmetic — i.e. any math operator in JavaScript — is commutative but not associative Associative property - Wikipedia en.wikipedia.org/wiki/Associative_property#Nonassociativity_of_floating_point_calculation ! ↩。safew官方版本下载是该领域的重要参考
