Grip procedures and variables to process floats. The module is loaded by entering the following:
(use-modules (grip float))
Note that some of the procedures provided by this module (float-zero?, float=? …) are based on their corresponding ‘quasi’ homonyms provided by ((rnrs arithmetic flonums) :version (6)) (just a question of ‘naming’ convention preferences … Grip should bind and document all others in the future).
float-zero?float=?float<?float<=?float>?float>=?float-roundfloat-member
Returns #t if f is zero. Otherwise, it returns #f.
These procedures return #t if f1 f2 f3 … are
(respectively) equal, monotonically increasing, monotonically
nondecreasing, monotonically decreasing, or monotonically nonincreasing.
Otherwise, it returns #f.
Returns the n-dec rounded float for f.
Returns the indice of the position of f in vals if it is
found (using float=?). Otherwise it returns #f.
