23.3.3.6 Arithmetic In Guile
The (gdb) module provides several functions for performing
arithmetic on <gdb:value> objects.
The arithmetic is performed as if it were done by the target,
and therefore has target semantics which are not necessarily
those of Scheme. For example operations work with a fixed precision,
not the arbitrary precision of Scheme.
Wherever a function takes an integer or pointer as an operand,
gdb will convert appropriate Scheme values to perform
the operation.
— Scheme Procedure:
value-add a b
— Scheme Procedure:
value-sub a b
— Scheme Procedure:
value-mul a b
— Scheme Procedure:
value-div a b
— Scheme Procedure:
value-rem a b
— Scheme Procedure:
value-mod a b
— Scheme Procedure:
value-pow a b
— Scheme Procedure:
value-not a
— Scheme Procedure:
value-neg a
— Scheme Procedure:
value-pos a
— Scheme Procedure:
value-abs a
— Scheme Procedure:
value-lsh a b
— Scheme Procedure:
value-rsh a b
— Scheme Procedure:
value-min a b
— Scheme Procedure:
value-max a b
— Scheme Procedure:
value-lognot a
— Scheme Procedure:
value-logand a b
— Scheme Procedure:
value-logior a b
— Scheme Procedure:
value-logxor a b
— Scheme Procedure:
value=? a b
— Scheme Procedure:
value<? a b
— Scheme Procedure:
value<=? a b
— Scheme Procedure:
value>? a b
— Scheme Procedure:
value>=? a b
Scheme does not provide a not-equal function,
and thus Guile support in gdb does not either.
