- float(x) -> floating point number
Convert a string or number to a floating point number, if possible.
- getint = <type 'int'>
- int(x=0) -> int or long
int(x, base=10) -> int or long

Data and other attributes inherited from Tkinter.Misc:
- getdouble = <type 'float'>
- float(x) -> floating point number
Convert a string or number to a floating point number, if possible.
- getint = <type 'int'>
- int(x=0) -> int or long
int(x, base=10) -> int or long
Convert a number or string to an integer, or return 0 if no arguments
are given. If x is floating point, the conversion truncates towards zero.
If x is outside the integer range, the function returns a long instead.
If x is not a number or if base is given, then x must be a string or
Unicode object representing an integer literal in the given base. The
literal can be preceded by '+' or '-' and be surrounded by whitespace.
The base defaults to 10. Valid bases are 0 and 2-36. Base 0 means to
interpret the base from the string as an integer literal.
