What is "0E-20"

Question

Im using a Model Based Testing tool (Conformiq). It generates test cases with value "0" but when i export those test cases in java, the value written there is "0E-20" What does that mean? What is "0E-20" ?

the code is somwhat like this :

new CQRecordNumber(
            /** value */
            (float)0E-20));

As per this Wiki page, xEy means x * 10^y, which, in your case, is 0 * 10^(-20)
