List Custom Float - Flexible float list syntax

Node Purpose: List Custom Float parses multiline text into a float list and returns the list alongside its count. It supports single values, lists, forward/reverse ranges, ranged strides, mixed Chinese/English punctuation, spaces, and mixed bracket styles. Float ranges are cleaned to avoid common accumulation noise.

Inputs

Name	Port	Type	Default	Range	Description
custom_text	-	STRING	``	multiline text	Text to parse using the flexible range/list syntax.

Outputs

Name	Type	Description
float_list	LIST	Parsed float values (list output).
count	INT	Length of float_list.

Features

• Loose parsing: accepts ,, ，, :, ：, [], 【】, (), （）, including mixed usage.
• Single values and lists: supports 1.0, .5, 1.0, 2.5, 3.
• Ranges and stride: supports 0-1, 1-0, 0-1:0.25, [0,1], [0,1), 【1，0】：0.2.
• Reverse ranges: expressions like 1-0 and [1,0]:0.2 expand in reverse order.
• Precision cleanup: output values are normalized to avoid artifacts like 0.30000000000000004.
• Order and duplicates preserved: values are emitted in written order and duplicates are kept.
• Robust defaults: empty input yields [0.0]; invalid fragments are ignored.

Typical Usage

• Single values and lists: 1.0, 0.5, 2.75
• Continuous range: [0,1]
• Strided range: [0,1):0.25
• Reverse range: 【1，0】：0.2
• Mixed input:

  1.0，0.5，2.75
  [0,1):0.25
  【1，0】：0.2
  .125
  

Notes & Tips

• : / ： means stride only in this node.
• Both range endpoints and stride support floating-point values.
• When no valid numbers are present, the node falls back to [0.0].
