BUG#32580 (mysqlbinlog cannot read binlog event generated by user variable usage):

Browse Source 
The client program 'mysqlbinlog' crashed when trying to print a User_var_log_event holding
a floating-point value since the format specifier for my_b_printf() does not support
floating-point format specifiers.

This patch prints the floating-point number to an internal buffer, and then writes
that buffer to the output instead.
