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

acosNon-libm

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].

acoshNon-libm

Inverse hyperbolic cosine function.

asinNon-libm

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].

asinhNon-libm

Inverse hyperbolic sine function.

atanNon-libm

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

atan2Non-libm

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

atanhNon-libm

Inverse hyperbolic tangent function.

cbrtNon-libm

Returns the cube root of a number.

cosNon-libm

Computes the cosine of a number (in radians).

coshNon-libm

Hyperbolic cosine function.

expNon-libm

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

exp2Non-libm

Returns 2^(self).

exp_m1Non-libm

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

hypotNon-libm

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().

lnNon-libm

Returns the natural logarithm of the number.

ln_1pNon-libm

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

log2Non-libm

Returns the base 2 logarithm of the number.

log10Non-libm

Returns the base 10 logarithm of the number.

powfNon-libm

Raises a number to a floating point power.

sinNon-libm

Computes the sine of a number (in radians).

sin_cosNon-libm

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

sinhNon-libm

Hyperbolic sine function.

tanNon-libm

Computes the tangent of a number (in radians).

tanhNon-libm

Hyperbolic tangent function.
