pub fn div_eps(dtype: DType) -> f32Expand description
A small dtype-specific epsilon for safe division (x / (y + eps)),
returned as f32.
The value is chosen per float format as the geometric mean (average in
log10 space) of two reference magnitudes: a scaled function of the format’s
minimum exponent and the format’s machine epsilon. This places eps
comfortably above the denormal/underflow floor while staying negligible
relative to typical activations, for each of f64/f32/f16/bf16. The
resulting constants are noted inline. dtype is the runtime float dtype of
the tensor being divided (e.g. x.dtype()). Panics on non-float dtypes.
