Module statrs::prec

source ·
Expand description

Provides utility functions for working with floating point precision

Constants§

  • DEFAULT_F64_ACC
    Default accuracy for f64, equivalent to 0.0 * F64_PREC
  • F64_PREC
    Standard epsilon, maximum relative precision of IEEE 754 double-precision floating point numbers (64 bit) e.g. 2^-53

Functions§

  • almost_eq
    Compares if two floats are close via approx::abs_diff_eq using a maximum absolute difference (epsilon) of acc.
  • convergence
    Compares if two floats are close via approx::relative_eq! and crate::consts::ACC relative precision. Updates first argument to value of second argument
