rnrs r5rs

The (rnrs r5rs (6)) library exports bindings for some procedures present in R5RS but omitted from the R6RS base library specification.

Scheme Procedure: exact->inexact z

Scheme Procedure: inexact->exact z

These procedures are identical to the ones provided by Guile’s core library. See Exact and Inexact Numbers, for documentation.

Scheme Procedure: quotient n1 n2

Scheme Procedure: remainder n1 n2

Scheme Procedure: modulo n1 n2

These procedures are identical to the ones provided by Guile’s core library. See Operations on Integer Values, for documentation.

Scheme Syntax: delay expr

Scheme Procedure: force promise

The delay form and the force procedure are identical to their counterparts in Guile’s core library. See Delayed Evaluation, for documentation.

Scheme Procedure: null-environment n

Scheme Procedure: scheme-report-environment n

These procedures are identical to the ones provided by the (ice-9 r5rs) Guile module. See Environments, for documentation.
