#182 Floating point error round(-3.77623) etc.

Topics

earlier versions of axiom gave:

  round(3.77623) => 4 
  round(-3.77623) => -5 ** wrong!

This was fixed by Dylan with Patch 2074:

axiom

round(3.77623)

$\label{eq1}4.0$

Type: Float

axiom

round(-3.77623)

$\label{eq2}-{4.0}$

Type: Float
