popen device outputs floats bigger than 1- 0 range

[pauluzs]

When using popen device with command "tee /dev/MYFIFO" or dd bs=1 of=/dev/MYFIFO
The output for 255 color values is 1.000015 instead of 1

Fist created a named pipe:
root@vuduo:# mkfifo /dev/MYFIFO
Then show the output
root@vuduo:# cat /dev/MYFIFO

Used moodlamp > static color to test this although 1.000015 values also appear in dynamic mode
