Numeric Functions
Numeric functions perform operations on
numeric data types such as INT and FLOAT.
ABS
number1=ABS(number2)
ABS returns the absolute
value of a number—that is, the magnitude of the value ignoring any
minus sign.
SET var1=ABS(2.143); → 2.143
SET var2=ABS(-10); → 10
SET var3=ABS(10); → 10
SET var4=ABS(-2.3); → 2.3BIN
binary_number=BIN(decimal_number)
BIN returns the binary
(base 2) representation of an integer value.
SET var1=BIN(1); → 1
SET var2=BIN(2); → 10
SET var3=BIN(3); → 11
SET var4=BIN(45); → 101101CEILING
number1=CEILING(number2)
CEILING returns the next
integer number that is higher than the input floating-point
number.
SET var1=CEILING(3.5); → 4
SET var2=CEILING(-3.5); → -3CONV
number1=CONV(number2,from_base,to_base)
CONV converts numbers from one base system to another.
Although CONV is, in essence, a
numeric function, it may return values that you may need to deal
with as strings (e.g., hexadecimal numbers).
The following CONV
statements convert the number 45 (base 10) into binary (base 2),
hexadecimal (base 16), and octal (base 8):
SET var1=CONV(45,10,2); → 101101
SET var2=CONV(45,10,16); → 2D
SET var3=CONV(45,10,8) ; → 55These statements convert the number 45 (base 2) into base 10, and converts 45 (base 8) into base 2:
SET var4=CONV(101101,2,10); → 45
SET var5=CONV(55,8,2); → 101101FLOOR
number1=FLOOR(number2)
FLOOR returns the largest
integer value not greater than X.
SET var1=FLOOR(3.5); → 3
SET var2=FLOOR(-3.5); → -4FORMAT
string=FORMAT(number,decimal_places ...
