I am building a massive fortress in creative and would like to be spared the monotomy of putting the floor in. I have access to commands and command blocks.
The modded server I am using is for running Minecraft version 1.7.2. I can't update it and it isn't my own server.

There's not an automatic way to do this in 1.7.2. If you're willing to be patient for 1.8 to come out, you can use the
/fill
command./fill x1 y1 z1 x2 y2 z2 gold_block
with the above coordinates. This fills your entire castle floor with gold blocks.
