Overview
This function makes fewer guarantees than the C runtime strtod :
• Only decimal notation is guaranteed to be supported. The handling of
scientific and hexadecimal notation is unspecified.
• Whether or not INF and NAN can be parsed is unspecified.
• The precision of the result is unspecified.
Function parameters
- str
-
the null-terminated string to read. Must not be NULL.
- endp
-
if not NULL, the address of the first invalid character (i.e. the next character after the parsed number) will be written to this pointer.
Return value
Returns the parsed double , or 0 if no number could be parsed.
Thread safety
It is safe to call this function from any thread.
