Fix float to byte conversion.

[Rem0o]

The conversion was using an implicit double between the float value to the byte value, which cause some issue with a software value of 100f, which resulted to 254 instead of 255.

Extracted the conversion as a function.

The problem simplified:

float floatValue = 100f;
float byteValue = floatValue * 2.55f;

// 254
byte a = (byte)((floatValue * 2.55f));
// 255
byte b = (byte)(byteValue);

// false
Console.WriteLine(a == b);
