HELP FILE

Question

Hello Gang,

Is there a HELP FILE for searching program commands?
I'm looking for how to round off a decimal number.

THANK YOU GANG
Barry

Answer 1

Which programming language? Python, JavaScript, ... ?

Answer 2

Assuming Python (your registered skill) + Android...

Little Drops Python Documentation (Google Play)
Offline, indexed, searchable documentation
Includes a copy of "Dive Into Python"

Python is also self-documenting. You can use print() or immediate mode to...
import decimal # extended floats

# view docstrings
decimal.__doc__
float.__doc__

# use the directory to get .method / .property names
dir(decimal)
dir(float)

float.is_integer.__doc__
# 'Returns true if the float is an integer'

# use the help system
help(decimal)
help(float.__round__)
