0001-change-float-to-t_float-in-Pd-extra.patch converts instances of 'float' to 't_float' in all classes of vanilla Pd's 'extra'. Also, a few constants and literals are defined with more decimals, and some float suffixes removed. The patch is intended for Pd-043.1test5.
Type 't_float' is already used in most of pd core code. The changes in the 'extra' classes would make them compliant with the core in this sense.
