Expand description

Parse a double from a string.

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.

§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.

§Availability

This function is available since SDL 3.2.0.
