Question

Using powerbuilder script, what is the easiest way to convert the string “0.5” to “50%”?

I’ve tried converting to Double first, but Double(“0.5”) returns 0..

Answer 1

Do you have any specific decimal separator other than . or ,?

In PB, the conversion from a string value to another type uses the regional settings. The same problem arises for converting other types like date or time.

Beware of the double (or float) type: floating point except for scientific computing is a painful path. Prefer the decimal type.

Here (with a coma as decimal separator) the following code seems to do what you are looking for:

dec value

value = dec("0,5")
value *= 100
value = int(value) //intermediate cast to integer to remove the decimal part

messagebox("percent", string(value)+"%")
