                        guint numeral_shape,
                        guint custom_shape_flags);

Render a floating-point value into `layout` in such a way that the layouting width does not needlessly exceed `col_width` . Optionally use unicode minus instead of hyphen.

#### Parameters

layout | Optional PangoLayout, probably preseeded with font attribute. |
str | a GString to store (not append!) the resulting string in. |
measure | Function to measure width of string/layout. | [scope call]
metrics | Font metrics corresponding to `measure` . |
val | floating-point value. Must be finite. |
col_width | intended max width of layout in the units that `measure` uses. A width of -1 means no restriction. |
unicode_minus | Use unicode minuses, not hyphens. |
numeral_shape | numeral shape identifier. |
custom_shape_flags | flags for using `numeral_shape` . |
