Warning

Symbols prefixed with either 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.

Note

To ruby-core: remember that this header can be possibly recursively included from extension libraries written in C++. Do not expect for instance __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.

Function Documentation

rb_int2big()

VALUE rb_int2big

(

intptr_t

i

)

Converts a C's intptr_t into an instance of rb_cInteger.

Parameters

[in]

i

Arbitrary intptr_t value.

Returns

An instance of rb_cInteger.

Note

This function always allocates Bignums, even if the given number is small enough to fit into a Fixnum.

Definition at line 3222 of file bignum.c.

rb_int2inum()

VALUE rb_int2inum

(

intptr_t

i

)

Converts a C's intptr_t into an instance of rb_cInteger.

Parameters

[in]

i

Arbitrary intptr_t value.

Returns

An instance of rb_cInteger.

Definition at line 3250 of file bignum.c.

rb_uint2big()

VALUE rb_uint2big

(

uintptr_t

i

)

Converts a C's intptr_t into an instance of rb_cInteger.

Parameters

[in]

i

Arbitrary intptr_t value.

Returns

An instance of rb_cInteger.

Note

This function always allocates Bignums, even if the given number is small enough to fit into a Fixnum.

Definition at line 3200 of file bignum.c.

rb_uint2inum()

VALUE rb_uint2inum

(

uintptr_t

i

)

Converts a C's uintptr_t into an instance of rb_cInteger.

Parameters

[in]

i

Arbitrary uintptr_t value.

Returns

An instance of rb_cInteger.
