- ParseToNumber( <Number>, <Text> )
- Parses the text and stores the result to a number a, which must be defined and free before the command is used.
- Example: Define
a = 3andtext1 = "6".ParseToNumber(a, text1)returns a = 6.
- Note: This is a scripting command which only sets the value of a number once. To convert a text text1 into a number which is updated dynamically, use FromBase(text1,10).
- ParseToNumber( <Text> )
- Parses the text and stores the result to a number.
- Example:
ParseToNumber("1+2+5-pi")creates the number a = 4.86.
- Note: See also ParseToFunction command.
