Basic Functions - Commodore VIC-20 Programmer's Reference Manual

VIC 20 BASIC FUNCTIONS
The intrinsic functions provided by BASIC are presented in the
following paragraphs. The functions may be called from any
program without further definition.
Arguments to functions are always enclosed in parentheses. In
the formats given for the functions in this chapter, the arguments
have been abbreviated as follows:
X and Y Represent any numeric expression
I and J Represent integer expressions
XS and YS Represent string expressions
If a floating point value is supplied where an integer is required,
BASIC will round the fractional portion and use the resulting
integer.
