floatColumn

Defines a nullable FLOAT column in the table, intended to store a Float.

This function creates and registers a column with the type FLOAT. While SQLite's REAL type stores an 8-byte floating-point number (equivalent to a Double), this function maps it to Kotlin's 4-byte Float for convenience when the full precision of a Double is not required, potentially saving memory in the application layer. The column is nullable by default.

Example:

object Sensors : KQLiteTable("sensors") {
    // A nullable FLOAT column for a temperature reading
    val temperature = floatColumn("temperature")

    // A non-null column for humidity percentage with a default value
    val humidity = floatColumn("humidity").notNull().default(0.0f)
}
