Syntax

$enableDecimals[enable]

Parameters

Parameter	Description
enable	Required (exactly one argument). yes, true, on or enable to enable decimals; no, false, off or disable to disable them. Any other value raises “Expected an enable-decimals boolean.”. A bare $enableDecimals is refused (“Invalid argument count”).

Return value

An empty string.

Behavior

• Without it (default: disabled), the non-integer results of $calculate[], $sum[], $sub[], $multi[], $divide[] and $sqrt[] are rounded to the nearest integer (halves round up: 2.5 gives 3, -2.5 gives -2), and $random without arguments returns an integer from 0 to 9.
• With $enableDecimals[yes], the results keep their decimals (and $random without arguments returns a decimal between 0 and 10).
• $enableDecimals[no] turns it off again.
• The effect is limited to the current command.

Examples

Calculation with decimals

$enableDecimals[yes]
$sendMessage[10 ÷ 3 = $calculate[10/3]]
; Displays: 10 ÷ 3 = 3.3333333333333335

Without decimals (default)

$sendMessage[10 ÷ 3 = $calculate[10/3]]
; Displays: 10 ÷ 3 = 3

Comparison before/after

$var[without;$calculate[10/3]]
$enableDecimals[yes]
$var[with;$calculate[10/3]]
$sendMessage[Without: $var[without] | With: $var[with]]

Notes

• Place before the calculations concerned.
• To round a calculation to N decimals, enable decimals first and then use $round[$calculate[...];N]: without $enableDecimals[yes], $calculate has already rounded its result to an integer ($round[$calculate[10/3];2] gives 3, whereas $round[2.567;2] gives 2.57 in any case).
• The enable argument is required: use $enableDecimals[yes].
