- ParseToNumber( <Number>, <String> )
- Parses the string 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.
Notes:
- 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].
- See also ParseToFunction command.
