Hello, first of all, Int stands for integer, which is generally divided into long integer and short integer. Short integers should be used here. Char is a character type, so you should choose the corresponding text type in ArcGIS. Float is a floating-point type that can store integers and decimals. If the field type changes, the field attributes will definitely change. For example, short integers may need to set aliases and default values, but text types need to set text length because different types of fields have different requirements. In addition, the double-precision type is similar to the floating-point type, and can store decimals.
