# FromDoubleToU8Fixed8Number Method

Summary
Converts a fractional number into a value that is consistent with the ICC specification format: u8Fixed8Number.
Syntax
C#
C++/CLI
Python
public static ushort FromDoubleToU8Fixed8Number(
double number
)
public:
static ushort FromDoubleToU8Fixed8Number(
double number
)
def FromDoubleToU8Fixed8Number(self,number):

#### Parameters

number
A fractional value.

#### Return Value

A value that is consistent with the ICC specification format u8Fixed8Number.

Remarks
• The ICC specification format (u8FixedU8Number) consist of a 2-bytes value that have its first bytes as the fixed part of the number, and the second bytes as the fractional part of the number.
Example
C#

public void IccCurveTagTypeExample()
{
IccProfileExtended iccProfile = new IccProfileExtended(fileName);

// preparing curve data, it consists of domain and range values
// if we have 1 value, it should be in the u8Fixed8Number format,
// and if we have more than 1 value, their type should be uInt16Number (ushort),
// in this example we will use 1 value, look at the VB example for more
// than 1 value curve data example
// ICC.1:2004-10 specification page 39.
double myDoubleValue = 1.5;
ushort[] curveData = new ushort[1];
curveData[0] = IccTools.FromDoubleToU8Fixed8Number(myDoubleValue);

// to read the value back from the curve data use the following function
myDoubleValue = IccTools.FromU8Fixed8NumberToDouble(curveData[0]);

// create the new iccCurveType
IccCurve iccCurve = new IccCurve(curveData);

// define the tag type
IccCurveTagType iccCurveTagType = new IccCurveTagType(iccCurve);

// add the new tag to the ICC Profile

// generate the new profile id
iccProfile.GenerateProfileId();

// update the icc array with the new changes
iccProfile.UpdateDataArray();

// write the Icc Profile into a new file
iccProfile.GenerateIccFile(IccfileName);
