TestNumericalNumber
Compares two numerical numbers
Syntax
ApCoCoATest.TestNumericalNumber(Found: RAT, Expected: RAT, Eps: RAT):LIST
Description
This function compares two numerical numbers. The difference between the two numbers must be smaller 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] -------------------------------
