Michael Jones	f1990feb35	[libc] add fuzz target for strtointeger functions ... The string to integer conversion functions are well suited to differential fuzzing, and this patch adds a target to enable just that. It also fixes a bug in the fuzzing comparison logic and changes atoi slightly to match the behavior described in the C standard.

Michael Jones	87c016078a	[libc] add atof, strtof and strtod ... Add the string to floating point conversion functions. Long doubles aren't supported yet, but floats and doubles are. The primary algorithm used is the Eisel-Lemire ParseNumberF64 algorithm, with the Simple Decimal Conversion algorithm as backup.
