You can multiply two numeric values together using the `*`

operator.

To multiply BCD numbers, you must import the ombcd.xmd file in your program. To multiply floating point numbers, import the omfloat.xmd 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 import "ombcd.xmd" unprefixed 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) import "omfloat.xmd" unprefixed 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:

import "ombcd.xmd" unprefixed 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 0.33 set tax-rate to 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.
