+This is a tiny but **fully loaded** printf, sprintf and snprintf implementation.  

 Primarily designed for usage in embedded systems, where printf is not available due to memory issues or in avoidance of linking against libc.  

 Using the standard libc printf may pull **a lot** of unwanted library stuff and can bloat code size about 20k. In this case the following implementation can be used.  

-Absolutely **NO dependencies** are required, printf.cpp brings all necessary routines, even its own fast ftoa conversion.

+Absolutely **NO dependencies** are required, printf.cpp brings all necessary routines, even its own fast `ftoa` conversion.

 

 If memory footprint is really a critical issue, floating point support can be turned off via the `PRINTF_FLOAT_SUPPORT` compiler switch.

 When using printf (instead of sprintf) you have to provide your own `_putchar()` low level function as console output.
