Function widen 

pub fn widen(
    source: &TypedTensor<Bf16, DynRank, Host>,
) -> Result<TypedTensor<f32, DynRank, Host>, Error>

Widen every stored value to f32, which is exact.

Errors

Returns a validation error carrying tenferro_tensor_core::ValidationError::ShapeDataLengthMismatch when the output shape cannot be built, which cannot happen for a shape that already exists.

Examples

use tenferro_bf16_proof::{conversion::widen, Bf16};
use tenferro_tensor::{DynRank, Host, TypedTensor};

let source = TypedTensor::<_, DynRank, Host>::from_host_vec_col_major(vec![2], vec![Bf16::from_f32(1.0), Bf16::from_f32(2.5)])?;
let widened = widen(&source)?;
assert_eq!(widened.as_slice(), &[1.0_f32, 2.5]);
