SDL_strtod - Parse a double from a string.

Defined in SDL3/SDL_stdinc.h

#include "SDL3/SDL.h"

double SDL_strtod(const char *str, char **endp);

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.

	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.

Returns the parsed double , or 0 if no number could be parsed.

It is safe to call this function from any thread.

This function is available since SDL 3.2.0.
