Hi @fokus237,
Here's some documentation about the different Alteryx data types. You'll likely want to use the Double numeric data type:
"A standard double-precision floating-point value. It uses 8 bytes and can represent values from +/- 1.7 x 10^-308 to 1.7 x 10^308 with 15 digits precision. A double uses a decimal that can be placed in any position. A double uses twice as many bits as a float and is generally used as the default data type for decimal values."
