Determine encoding for floating point values

.determineEncoding(
  x,
  precision = "single",
  decimals = NULL,
  range = NULL,
  fields = NULL
)

Arguments

x: numeric(.)
a set of numeric values for which to determine the floating point encoding.
precision: character(1)
option that determines the configuration of the floating point encoding. Possible values are "half" [1.5.10], "bfloat16" [1.8.7], "tensor19" [1.8.10], "fp24" [1.7.16], "pxr24" [1.8.15], "single" [1.8.23], "double" [1.11.52] and "auto" (where the positions are determined based on the provided numeric values in x; not supported yet).
decimals: integer(1)
the number of decimal digits that should be reliably represented, not supported yet.
range: numeric(2)
the ratio between the smallest and largest possible value to be reliably represented, not supported yet.
fields: list(3)
list that controls how many bits are allocated to sign, exponent and mantissa for encoding the numeric values.
