This does not work for negative numbers !

+1 for disable floats in pre_build to save memory.

Especially if string.format and other similar side effects are not fixed.

The problem of string.format have fixed, the discussion is here.

Well the last working build was

NodeMCU 0.9.5 build 20150123 powered by Lua 5.1.4

this version also appears to work with 512K and 4m Flash

flash is 512K
latest nodemcu prebuild at 115200 baud errors

Adding float may not be the issue but things have gone awry since float was attempted.

I'm using the nodemcu prebuilds since the windows eclipse IDE by CHERTS does not compile error free for nodemcu-firmware so I can't get the float out of the compile.
The default for float should be to have it selected out of the prebuild's not selected in as it is now.
