[Lazarus] procedure FloatToDecimal

[Héctor Fiandor Rosario]

Dear sirs:

I need to convert a Float to a number with two decimal places in a Lazarus 
Project for Windows..

I am thinking to use the following procedure:

procedure FloatToDecimal(var DecVal: TFloatRec; const Value; ValueType: 
TFloatValue; Precision, Decimals: Integer);

but I dont know what to write in some of the arguments.

Thanks in advance for your help,

yours truly,

Ing. Héctor F. Fiandor
