Subject: [PATCH 06/24] Better documentation for [string_of_float]. (#11353)
|
|
|
|
Better documentation for [string_of_float] (and [Float.to_string])
|
|
with similar warnings for [print_float] and [prerr_float] in a similar way.
|
|
|
|
(cherry picked from commit 40113fbc73930b41a7a2df468de18c94feeefdf5)
