sprintf allocates mem from heap if use %f

• Messages sorted by:[ date ][ thread ][ subject ][ author ]

Hi All,

I discovered that when I use floating point formats in calls to sprintf() 
(eg %f) then a small amount of dynamic memory is required. My system does 
not require any dynamic memory but I would like to be able to use sprintf() 
to format floating point values. Is there anyway of not using dynamic 
memory, short of patching the library (newlib) or writing my own floating 
point formating routine.

TIA
David Williams.
