Frequently Asked Questions — Math & Analytics
How does ToolFlux Lab ensure numerical accuracy?
Calculations run in native IEEE-754 double-precision arithmetic. Rounding policies are strictly documented and applied only at the final presentation layer to prevent cumulative rounding distortion.
Can the GPA Calculator accommodate 4.0 and 5.0 university scales?
Yes. The GPA suite supports standard 4.0 and 5.0 weighted credit scales with customizable course loads, credit hours, and target GPA simulation.
What percentage modes are supported in the Master Percentage Studio?
It supports 6 comprehensive workflows: Percentage of a number, What percentage is A of B, Percentage increase/decrease, Retail discount with optional sales tax, Tip & bill splitting, and Relative percentage difference.
