The numeric data types can be classified into two categories by precision:

  • Exact numeric data types
    • Integer data types: TINYINT, SAMLLINT, MEDIUMINT, INTEGER, and BIGINT
    • Fixed-point data types: DECIMAL and NUMERIC
  • Approximate numeric data types: FLOAT, REAL, and DOUBLE PRECISION
