ABSOLUTE VALUES
The function ABS finds the absolute value of a
number: the value of the numeric part,
disregarding the sign. The function changes
negative numbers to positive numbers, but has no
effect on positive numbers.
PRINT ABS(123.456)
displays e 123.456' - no change. But
PRINT ABS(-543.345)
displays e 543.345 '- the minus sIgn has been
removed.
INTEGER CONVERSION
The function INT removes the fractional part of a
number and returns the next lower whole number.
Try:
PRINT INT(123.4567)
Only the whole number part - 123 - is displayed.
Be careful with numbers less than zero. The INT
function finds the first whole number lower then
the number you give it. This means that for
negative numbers the answer is not the whole part
of the initial number, but one less (or minus one
morel), Therefore:
PRINT INT(-2.875)
displays t_3'.
