[Gambas-user] Inbuilt function to check if a string contains a valid number

[vikram]

Hi,

Is there an inbuilt function in Gambas 2 (2.21) to check if a string contains a 
valid number?


Thanks,
Vikram Nair

No, but you can do that:

DIM MyNumber AS Float
TRY MyNumber = Val(MyString)
IF ERROR THEN PRINT Not a valid number

In Gambas3, IsNumber() does what you want. But not in Gambas 2, beware!
