ArcGIS Field Data Types

ArcGIS Data Types

File Geodatabase data types are the same as ArcGIS data types.

In ArcGIS Desktop 4 Numeric data type:

  1. Short integer
  2. Long integer
  3. Float (single-precision floating-point numbers)
  4. Double (double-precision floating-point numbers)

ArcGIS Geodatabase Data Deacription

The following table lists for file and personal Geodatabases’s data types, their ranges, and storage requirements.

Data typeStorable rangeSize (Bytes)Applications
Short integer-32,768 to 32,7672Numeric values without fractional values within specific range; coded values
Long integer-2,147,483,648 to 2,147,483,6474Numeric values without fractional values within specific range
Float (single-precision floating-point number)approximately -3.4E38 to 1.2E384Numeric values with fractional values within specific range
Double (double-precision floating-point number)approximately -2.2E308 to 1.8E3088Numeric values with fractional values within specific range

Data type, Precision, and Scale

Data types and their possible precision and scale values you can set in ArcGIS Desktop.

Data typePrecision (maximum field length)Scale (maximum number of decimal places)
Short integer*1–5 (Oracle)0
Long integer**6–9 (Db2 and Informix)6–10 (Oracle)0
Float1–61–6
Double7+0+

Number ranges and store them in a database or desktop Geodatabase
