RBIMPL
or rbimpl
are implementation details. Don't take them as canon. They could rapidly appear then vanish. The name (path) of this header file is also an implementation detail. Do not expect it to persist at the place it is now. Developers are free to move it anywhere anytime at will. __VA_ARGS__
is always available. We assume C99 for ruby itself but we don't assume languages of extension libraries. They could be written in C++98. Definition in file double.h.
VALUE rb_float_new | ( | double | d | ) |
Converts a C's double
into an instance of rb_cFloat.
[in] | d | Arbitrary double value. |

VALUE rb_float_new_in_heap | ( | double | d | ) |
