Module ops

This mod re-exports the correct versions of floating-point operations with unspecified precision in the standard library depending on whether the libm crate feature is enabled.

All the functions here are named according to their versions in the standard library.

Traits

FloatPow

This extension trait covers shortfall in determinacy from the lack of a libm counterpart to f32::powi. Use this for the common small exponents.

Functions

acos

Computes the arccosine of a number. Return value is in radians in the range [0, pi] or NaN if the number is outside the range [-1, 1].

acosh

Inverse hyperbolic cosine function.

asin

Computes the arcsine of a number. Return value is in radians in the range [-pi/2, pi/2] or NaN if the number is outside the range [-1, 1].

asinh

Inverse hyperbolic sine function.

atan

Computes the arctangent of a number. Return value is in radians in the range [-pi/2, pi/2];

atan2

Computes the four-quadrant arctangent of y and x in radians.

atanh

Inverse hyperbolic tangent function.

cbrt

Returns the cube root of a number.

cos

Computes the cosine of a number (in radians).

cosh

Hyperbolic cosine function.

exp

Returns e^(self), (the exponential function).

exp2

Returns 2^(self).

exp_m1

Returns e^(self) - 1 in a way that is accurate even if the number is close to zero.

hypot

Compute the distance between the origin and a point (x, y) on the Euclidean plane. Equivalently, compute the length of the hypotenuse of a right-angle triangle with other sides having length x.abs() and y.abs().

ln

Returns the natural logarithm of the number.

ln_1p

Returns ln(1+n) (natural logarithm) more accurately than if the operations were performed separately.

log2

Returns the base 2 logarithm of the number.

log10

Returns the base 10 logarithm of the number.

powf

Raises a number to a floating point power.

sin

Computes the sine of a number (in radians).

sin_cos

Simultaneously computes the sine and cosine of the number, x. Returns (sin(x), cos(x)).

sinh

Hyperbolic sine function.

tan

Computes the tangent of a number (in radians).

tanh

Hyperbolic tangent function.
