L_LTCLR_API L_DOUBLE L_2bFixed2bNumberToDouble(uNumber)

L_UINT32 uNumber;

/* integer value */

Converts a 2-bytes fixed, 2-bytes fraction number format into a double fractional value.

Parameter

Description

uNumber

Value that represents the 2-bytes fixed, 2-bytes fraction number value to convert.

Returns

A double value that contains a fraction number representing the value passed to the function.

Comments

This function is used for ICC profiles purposes. The number passed must be one of the following types: L_IccS15Fixed16Number or L_IccU16Fixed16Number.

Each of these types is 4-bytes, divided into 2-bytes that contain the fixed part of the number, and 2-bytes that contain the fractional part of the number.

The (2b) found in the function name means (2-bytes).
