24.4.3.6 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,
ROCGDB 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 ROCGDB does not either.
