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 self (y) and other (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.
