Crate ieee_apsqrt

Performs square root operations on IEEE 754 single, double, and quad precision floats using rustc_apfloat. See the readme for more background.

Functions

• sqrt_accurate
  Calculate the square root of the given floating point bits, with the given rounding mode. Results are completely accurate, but each iteration is twice as costly as with sqrt_fast. Returns the result, and the number of Newton-Raphson iterations that were needed. Can operate on u32 or u64 values, which are interpreted as the bit representations of IEEE 754 single- and double-precision floats, respectively.
• sqrt_fast
  Calculate the square root of the given floating point bits, with the given rounding mode. Results are accurate to within 2 ulps. Returns the result, and the number of Newton-Raphson iterations that were needed. Can operate on u32, u64, or u128 values, which are interpreted as the bit representations of IEEE 754 single-, double-, and quad-precision floats, respectively.
