formatFloat

formatFloat :: (
    value: Any,
    width := -1,
    trailing_width := -1,
    mode := FormatFloat.Mode.DECIMAL,
    zero_removal := FormatFloat.Zero_Removal.YES
) -> FormatFloat

Parameters

value: Any

width := -1

the least number of characters; shorter text is padded with spaces on the left. -1 for no padding.

trailing_width := -1

digits after the decimal point; 6 when negative.

mode := FormatFloat.Mode.DECIMAL

.DECIMAL, .SCIENTIFIC or .SHORTEST.

zero_removal := FormatFloat.Zero_Removal.YES

whether zeros at the end of the fraction are dropped: .YES drops them all, .ONE_ZERO_AFTER_DECIMAL keeps one, .NO keeps them. With trailing_width set, dropped zeros leave spaces so columns still line up.

Returns

FormatFloat

assert(tprint("%", formatFloat(3.14159, trailing_width = 2)) == "3.14");
