cbrt() returns incorrect answers

[Former user]

Originally reported on Google Code with ID 411 ``` What steps will reproduce the problem? 1. cbrt(5^3) = 5 (correct) 2. cbrt(7^3) = 7 (correct) 3. cbrt(6^3) = 5.6 (what?!?)

What is the expected output? What do you see instead? cbrt(6^3) = 6, not 5.6 Other numbers are wrong as well cbrt(8^3) = 7.6 cbrt(9^3) = 8.6

What version of the product are you using? On what operating system? Speed Crunch 0.10.1 Windows 7 Professional 64-Bit SP1 Intel Core i7-2600 @ 3.4 GHz 8.00 GB of ram

Please provide any additional information below. Error appears on every system I have tested (3 different windows installs, all 64 bit) ```
