Element-wise inverse cosine.

Usage

prim_acos(x)

Arguments

x

(arrayish)
One input. Can be any float data type. An R value materializes at its default data type.

Value

(arrayish)
Has the input's shape and data type.

Implemented Rules

StableHLO

Lowers to hlo_acos(), an op of the CHLO dialect, a higher-level companion to StableHLO that is lowered to it during compilation. See chlo.acos.
