Return type: Integer The product of its operands.
Returns:
Syntax
numeric-expression * numeric-expression
You can multiply two numeric values together using the * operator.
To multiply BCD numbers, you must include the ombcd.xin file in your program. To multiply floating point numbers, include the omfloat.xin file.
You can multiply values of mixed data types (for example, BCD numbers and integers) as long as you follow the rules listed in Operations with mixed data types.
Always surround arithmetic operators with spaces.
BCD Example:
; Distance = speed * time
include "ombcd.xin"
process
local bcd kilometers-per-hour initial {90}
local bcd hours initial {1.5}
local bcd distance
set distance to kilometers-per-hour * hours
output "Distance is "
|| "d" % distance
|| " kilometers.%n"
; Output: 'Distance is 135 kilometers'.
Floating Point Example:
; E = IR (volts = amperes * ohms)
include "omfloat.xin"
process
local float amperes initial {1.9237}
local float ohms initial {60}
local float volts
set volts to amperes * ohms
output "Volts = "
|| "d" % volts
|| "%n"
; Output: 'Volts = 115.422'
Mixed Data Type Example:
include "ombcd.xin"
process
local integer apples-per-child initial {6}
local integer school-children initial {28}
local integer total-apples
local bcd apple-price
local bcd tax-rate
local bcd total-price
set total-apples to apples-per-child * school-children
output "Total apples = "
|| "d" % total-apples
|| "%n"
set apple-price to bcd 0.33
set tax-rate to bcd 0.05
set total-price to total-apples * apple-price * (1 + tax-rate)
output "Total price = "
|| "<$,NNZ.ZZ>" % total-price
|| "%n"
; Output: 'Total apples = 168'
; 'Total price = $58.21'
The word times is a deprecated synonym for *.
For floating point numbers, overflow and underflow values return infinity and zero, respectively.
BCD numbers cannot overflow, but returns 0 on underflow.
Integers cannot underflow, but overflow returns an incorrect answer depending on the operating system.
