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
