Hello! I’m trying to understand how much storage space is in 100,000 vectors. Does anyone know what precision() is used for each float in a pinecone vector? ---

Hey @byzan.solutions, each dimension on a single vector consumes 4 bytes of memory and storage per dimension. See: “Dimensionality of vectors” section in [Choosing index type and size](https://docs.pinecone.io/docs/choosing-index-type-and-size#dimensionality-of-vectors) ---

Hey @byzan.solutions , more specifically we use 32-bit floats as defined in IEEE 754, which I think is basically the industry standard at this point (Like Java’s `float` type, or Rust’s `f32`).
