Module type `Crlibm.S`Source

Common functions to the four rounding modules below.

In order for the interface to be light, the functions with standard mathematical names are not documented.

Sourceval exp : float -> float

Sourceval expm1 : float -> float

expm1 x returns exp x -. 1. in a way that is accurate even for values of x near zero.

Sourceval log : float -> float

Sourceval log1p : float -> float

log1p x returns log(x +. 1.) in a way that is accurate even for values of x near zero.

Sourceval cos : float -> float

Sourceval sin : float -> float

Sourceval tan : float -> float

Sourceval cospi : float -> float

cospi x returns cos(π·x).

Sourceval sinpi : float -> float

sinpi x returns sin(π·x).

Sourceval tanpi : float -> float

tanpi x returns tan(π·x).

Sourceval asin : float -> float

Sourceval acos : float -> float

Sourceval atan : float -> float

Sourceval asinpi : float -> float

asinpi x returns (asin x)/π ∈ [-0.5, 0.5].

Sourceval acospi : float -> float

acospi x returns (acos x)/π ∈ [0., 1.].

Sourceval atanpi : float -> float

atanpi x returns (atan x)/π ∈ [-0.5, 0.5].

Sourceval cosh : float -> float

Sourceval sinh : float -> float

Sourceval log2 : float -> float

Sourceval log10 : float -> float
