/**

 * SECTION:liboilfuncs-conv

 * @title: Type Conversion

 * @short_description: Type conversion

 *

 * The functions in this section perform type conversion.

 *

 * The <i>convert</i> functions convert value from the source type to

 * the destination type.  Conversion of values outside the

 * destination range are saturated to the destination range.

 *

 * The <i>scaleconv</i> functions multiply the source values by a

 * constant factor before converting to the destination type.  Conversion

 * of values outside the destination range are clamped to the

 * destination range.

 * 

 * Conversion of values from floating point types to integer types

 * is done using a round-to-nearest policy.  Rounding of half-integers

 * is undefined and may vary between implementations.
