Hi Rohit,
baselibc does support floating point formatting, but it is not enabled
by default. To enable it, set the following syscfg setting to 1 in your
target:
FLOAT_USER
baselibc's float printf support is a bit limited. In particular, it
ignores precision specifiers and always prints three digits after the
decimal point.
