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.
