Module Framac_ival.Floating_pointSource

Floating-point operations.

Sourcetype c_rounding_mode =
  1. | FE_ToNearest
  2. | FE_Upward
  3. | FE_Downward
  4. | FE_TowardZero

Rounding modes defined in the C99 standard.

If s is parsed as (n, l, u), then n is the nearest approximation of s with the desired precision. Moreover, l and u are the most precise float such that l <= s <= u, again with this precision.

Consistent with logic_real definition in Cil_types.

parse s parses s and returns the parsed float and its kind (single, double or long double precision) according to its suffix, if any. Strings with no suffix are parsed as double.

Sourceval pretty_normal : use_hex:bool -> Format.formatter -> float -> unit
Sourceval pretty : Format.formatter -> float -> unit
Sourcetype sign =
  1. | Neg
  2. | Pos
Sourceexception Float_Non_representable_as_Int64 of sign
Sourceval truncate_to_integer : float -> Z.t

Raises Float_Non_representable_as_Int64 if the float value cannot be represented as an Int64 or as an unsigned Int64.

Sourceval bits_of_max_double : Z.t

binary representation of -DBL_MAX and DBL_MAX as 64 bits signed integers

Sourceval bits_of_most_negative_double : Z.t
Sourceval bits_of_max_float : Z.t

binary representation of -FLT_MAX and FLT_MAX as 32 bits signed integers

Sourceval bits_of_most_negative_float : Z.t
Sourceval fround : float -> float

Rounds to nearest integer, away from zero (like round() in C).

Sourceval trunc : float -> float

Rounds to integer, toward zero (like trunc() in C).
