A(n) float is:

• A precise number by including values after the decimal place
• A programming statement that directs control flow - it uses BOOLEAN expressions to make a choice between different paths (IF (condition) THEN (path1) ELSE (path2)
• A data type that can have only 2 values - TRUE or FALSE
• A whole number, it does not have any digits after a decimal.
