Match whole lines but remove specific word/expression directly from match-CodePudding

I have a some multi-lines files that have strange format. It looks a little like this:

line 1: text1 0.2348953147573326nope text2Text3 text4\n
line 2: blabla-blabla\n
[...]

How can I match whole lines of data but remove those "0.2348953147573326" (random float values glued to some words) directly from the regex match? The expected regex match would be like:

text1 nope text2Text3 text4\n
blabla-blabla\n[...]

If the number you want to remove is always a decimal, this would do the job:

let str = "text1 0.2348953147573326nope text2Text3 text4\n blabla-blabla\n[...]";
console.log(str.replace(/\d \.\d /, ""));

Expression explained:

\d : matches a digit (0-9) 1 or more times
\.: matches a dot character (.)
\d: as said before, matches a digit (0-9) 1 or more times

Ok, I figured out solution in terms of fit regex pattern. For me worked:

(^.  (?=\d \.\d )|(?<=\d \.\d )\D. $)|^((?!\d \.\d ).)*$

(^. (?=\d \.\d ): match stuff before excluded expression (in my example it is float value),
(?<=\d \.\d )\D. $): match stuff after excluded expression,
^((?!\d \.\d ).)*$: match lines that doesn't contain excluded expression
