Module Float.SingleSource

Single precision operations.

Single precision numbers are stored inside OCaml's floats, that are actually double precion, but rounding is done to single precision.

Operations

Sourceval add_near : t -> t -> t
Sourceval add_up : t -> t -> t
Sourceval add_down : t -> t -> t
Sourceval add_zero : t -> t -> t

Addition

Sourceval sub_near : t -> t -> t
Sourceval sub_up : t -> t -> t
Sourceval sub_down : t -> t -> t
Sourceval sub_zero : t -> t -> t

Subtraction

Sourceval mul_near : t -> t -> t
Sourceval mul_up : t -> t -> t
Sourceval mul_down : t -> t -> t
Sourceval mul_zero : t -> t -> t

Multiplication

Sourceval mulz_near : t -> t -> t
Sourceval mulz_up : t -> t -> t
Sourceval mulz_down : t -> t -> t
Sourceval mulz_zero : t -> t -> t

Special multiplication where 0 times an infinity is 0, not NaN. This is particularly useful for interal bounds.

Sourceval div_near : t -> t -> t
Sourceval div_up : t -> t -> t
Sourceval div_down : t -> t -> t
Sourceval div_zero : t -> t -> t

Division

Sourceval divz_near : t -> t -> t
Sourceval divz_up : t -> t -> t
Sourceval divz_down : t -> t -> t
Sourceval divz_zero : t -> t -> t

Special division where 0 / 0 is 0, not NaN. This is particularly useful for interal bounds.

Sourceval mod_near : t -> t -> t
Sourceval mod_up : t -> t -> t
Sourceval mod_down : t -> t -> t
Sourceval mod_zero : t -> t -> t

Remainder.

Sourceval square_near : t -> t
Sourceval square_up : t -> t
Sourceval square_down : t -> t
Sourceval square_zero : t -> t

Square.

Sourceval sqrt_near : t -> t
Sourceval sqrt_up : t -> t
Sourceval sqrt_down : t -> t
Sourceval sqrt_zero : t -> t

Square root.

Sourceval round_int_near : t -> t
Sourceval round_int_up : t -> t
Sourceval round_int_down : t -> t
Sourceval round_int_zero : t -> t

Rounding to an integer.

Sourceval of_double_near : t -> t
Sourceval of_double_up : t -> t
Sourceval of_double_down : t -> t
Sourceval of_double_zero : t -> t

Rounding from double to single precision.

Sourceval of_int_near : int -> t
Sourceval of_int_up : int -> t
Sourceval of_int_down : int -> t
Sourceval of_int_zero : int -> t
Sourceval of_int_cur : int -> t

Conversion from int with rounding.

Sourceval of_int64_near : int64 -> t
Sourceval of_int64_up : int64 -> t
Sourceval of_int64_down : int64 -> t
Sourceval of_int64_zero : int64 -> t
Sourceval of_int64_cur : int64 -> t

Conversion from int64 with rounding.

Code from Zarith to convert from Z.t to float using the current rounding mode. We add a version for single precision rounding.

Sourceval round_z_to_single : Z.t -> bool -> t
Sourceval z_to_single : Z.t -> t
Sourceval of_z_near : Z.t -> t
Sourceval of_z_up : Z.t -> t
Sourceval of_z_down : Z.t -> t
Sourceval of_z_zero : Z.t -> t

Conversion from Zarith with rounding.

Floating-point format characteristics

Sourceval mantissa_bits : int
Sourceval exponent_bits : int
Sourceval exponent_bias : int
Sourceval min_exponent : int
Sourceval max_exponent : int
Sourceval nan_infinity_exponent : int
Sourceval min_denormal : t
Sourceval min_normal : t
Sourceval max_normal : t
Sourceval max_exact : t
Sourceval ulp : t

Units in the last place (relative precision).

Sourceval rep_of_bits : int32 -> bit_float
Sourceval bits_of_rep : bit_float -> int32
Sourceval to_bits : t -> int32
Sourceval of_bits : int32 -> t
Sourceval succ : t -> t
Sourceval pred : t -> t

Returns the float immediately follownig or preceeding the argument.

Sourceval succ_zero : t -> t
Sourceval pred_zero : t -> t

As succ and pred, but does not cross zero.

Sourceval of_string_up : string -> t
Sourceval of_string_down : string -> t

Conversion from string.
