Transformation text to number

Question

Hi,
I picked up a script for a
calculated column.
In one column, I have the values ​​of
disk space used in "text" format.
They can be in MB, GB OR
TB. The counts have a
point of separation. Ex: 15.6 GB
In my column calculated, I want to
get the result in Go AND with
commas. When I apply the script, I end up with
the same value without the indication
text and with the point. (ex: 15.6)
and the format remains text, excluding
the result I want is 15.6 (decimal
or integer if I want)
I put the scripts, if anyone can help
me.  thank you.
= if (if (iserror (find ("KB"
[used space])), FALSE,
TRUE); "0" if (if (iserror
(find ("MB" [used
space])); FALSE; TRUE);
Concatenate ("0;"
SUBSTITUTE (SUBSTITUTE ([used space],
"MB", "");
if (if (iserror (find ("TB"
[used space])), FALSE,
TRUE); SUBSTITUTE (SUBSTITUTE ([used
space], "TB",
"0"), "", "");
SUBSTITUTE (SUBSTITUTE ([used space]
"GB"; "")"

Right! I've been playing with the workbook for a while and have found that the model is failing to recognise numbers stored as text as actual numbers even when the VALUE function is used. As a result, I have written logic that will manually break down the
text and then reconstruct it as a number.
We shouldn't normally require a solution anywhere near this complicated for the given scenario but due to what appears to be a character glitch/bug in the model there appears to be no easy way to convert the text into a number. The DAX formula below is
quite complex compared to the one originally proposed - I have already added this column in the OneDrive copy ;)
=
SUBSTITUTE(
SWITCH(
RIGHT('synthese-serveur'[used space], 2),
"MB",
VALUE(
PATHITEM(
SUBSTITUTE(
PATHITEM(
SUBSTITUTE(
'synthese-serveur'[used space],
"|"
1
"|"
1
+
PATHITEM(
SUBSTITUTE(
PATHITEM(
SUBSTITUTE(
'synthese-serveur'[used space],
"|"
1
"|"
2
)/100
)/1000,
"GB",
VALUE(
PATHITEM(
SUBSTITUTE(
PATHITEM(
SUBSTITUTE(
'synthese-serveur'[used space],
"|"
1
"|"
1
+
PATHITEM(
SUBSTITUTE(
PATHITEM(
SUBSTITUTE(
'synthese-serveur'[used space],
"|"
1
"|"
2
)/100
"TB",
VALUE(
PATHITEM(
SUBSTITUTE(
PATHITEM(
SUBSTITUTE(
'synthese-serveur'[used space],
"|"
1
"|"
1
+
PATHITEM(
SUBSTITUTE(
PATHITEM(
SUBSTITUTE(
'synthese-serveur'[used space],
"|"
1
"|"
2
)/100
)* 1000
If this is working as expected, let me know and I will provide an explanation of what is happening in the DAX formula.
Edit: To minimize the replication of DAX code, you can go for a two column solution where [used space Go Part 1] is defined as:
=VALUE(
PATHITEM(
SUBSTITUTE(
PATHITEM(
SUBSTITUTE(
'synthese-serveur'[used space],
"|"
1
"|"
1
+
PATHITEM(
SUBSTITUTE(
PATHITEM(
SUBSTITUTE(
'synthese-serveur'[used space],
"|"
1
"|"
2
)/100
And [used space Go Part 2] is defined as:
=SUBSTITUTE(
SWITCH(
RIGHT('synthese-serveur'[used space], 2),
"MB", 'synthese-serveur'[used space Go Part 1] / 1000,
"GB", 'synthese-serveur'[used space Go Part 1],
"TB", 'synthese-serveur'[used space Go Part 1] * 1000
The main concern with this approach is that it will result in a larger model/file size due to the relatively high number of distinct values in the columns.
