TestNumericalNumber

Compares two numerical numbers

Syntax

ApCoCoATest.TestNumericalNumber(Found: RAT, Expected: RAT, Eps: RAT)

Description

This function compares two numerical numbers and returns "TRUE", if the difference isn't greater than Eps.

  • @param Found: The numerical value that was computed

  • @param Expected: The numerical value that should be computed

  • @param Eps: The allowed difference between the two values

  • @return A list. First entry is a boolean, its value is TRUE, if the test has been passed. If FALSE, the list contains also the expected and the found number.

Example

F := 3.14159265; E := 3.141;
ApCoCoATest.TestNumericalNumber(F,E,0.01);

[TRUE]

F := 3.14159265; E := 3.141;
ApCoCoATest.TestNumericalNumber(F,E,0.0001);

[FALSE, 62831853/20000000, 3141/1000]
