Conversion of Exponential Notation to Decimal numbers

[43918084]

I have a field that contains both numeric and text.  For some numeric value, the number is 580886158980001000000.

But Qliksense returns  5.8088615898e+20.

I have tried to use Num(Replace("Arr Lcl Num Ath", ',', '.'), '(dec)') as ALN

But the result return "-"

Hope I can have some expert guidance
