Converting Text to Number

Hi,
Im in the process of pulling web data and the data is being pulled all in text format, i am looking for a way to change the Min and Max temperature from the weather tables i have pulled into Num format so i can put it into a chart as currently it doesn't work.

LOAD @1 as PH_Direction,

     @2 as PH_Speed,

     @3 as PH_Time,

     @4 as PH_UV,

     @5 as PH_RAmount,

     @6 as PH_CoR,

     @7 as PH_Min,

     @8 as PH_Max,

     @9 as PH_Summary,

     @10 as PH_Date

This is what i currently have for this section. PH_Min and PH_Max are Min and Max temperatures.

Cannot seem to find an appropriate answer on the community

if you want to convert into numeric then:

Num(fieldName)

Look into number interpretation functions like Num#(), for example

LOAD

..

     Num#(@7,'#,00',',','.') as PH_Min,

     Num#(@8,'#,00',',','.') as PH_Max,

Thanks, it seems to be working however since the data being pulled is displayed like this
19°C
it displays it as a "-" in the table.
How do i format it to remove the " °C " at the end

MarcoWedel

can you post a sample of your data and your format variables as well?

thanks

PurgeChar(@7,'°C') as PH_Min

Maybe use purgechar()

PurgeChar(FIELD,'°C') As FIELD

or to keep the unit but get a dual value (incl. underlying numerical value):

Dual(@7, PurgeChar(@7,'°C')) as PH_Min


hope this helps

Im having difficulty uploading my QVW file as there doesnt seem to be anywhere to do it, but my entire script for that section is

//......................................Port Hedland

LOAD @1 as PH_Direction,

     @2 as PH_Speed,

     @3 as PH_Time,

     @4 as PH_UV,

     @5 as PH_RAmount,

     @6 as PH_CoR,

     @7 as PH_Min,

     @8 as PH_Max,

     @9 as PH_Summary,

     @10 as PH_Date

FROM

[http://www.weatherzone.com.au/wa/pilbara/port-hedland]

(html, codepage is 1252, no labels, table is @6, filters(

Remove(Row, Pos(Top, 13)),

Remove(Row, Pos(Top, 12)),

Remove(Row, Pos(Top, 8)),

Remove(Col, Pos(Top, 15)),

Remove(Col, Pos(Top, 13)),

Remove(Col, Pos(Top, 11)),

Remove(Col, Pos(Top, 9)),

Remove(Col, Pos(Top, 7)),

Remove(Col, Pos(Top, 5)),

Remove(Col, Pos(Top, 3)),

Rotate(right),

Remove(Row, Pos(Top, 1))

));

PH_Date PH_Summary PH_Max PH_Min PH_CoR PH_Direction PH_RAmount PH_UV PH_Speed
FriMay 20Sunny33°C21°C20%E< 1mmHigh13km/h
SatMay 21Increasing sunshine31°C22°C10%WNW< 1mmVery High9km/h
SunMay 22Mostly sunny32°C19°C30%SSE< 1mmHigh20km/h
ThuMay 26Sunny30°C20°C40%SSE< 1mm 9km/h
MonMay 23Sunny32°C20°C30%ESE< 1mmHigh28km/h
TueMay 24Sunny31°C19°C10%ESE< 1mmHigh15km/h
WedMay 25Sunny30°C21°C30%SE< 1mm 10km/h

So i would like to be able to have the temperatures and other numbers in a number format so i can chart them. if i format them at the moment using Num() the field will show up as "-" so i need to be able to remove °C from each

The dual didn't seem to do anything? although the PurgeChar by itself seemed to work perfectly!
