Added in 3.3


Returns the result of the specified operations. You can perform multiple operations.

Can calculate extremely high numbers, but can only be used on whole numbers, not decimal/float/fractions. Does not have the limitation in $calc() where any term or output value 2^96 or higher is zero.

Any term containing non-zero fraction replaced by zero. Output has any fraction removed.

Arithmetic Operators.

Operations can be grouped with parentheses.

Same operators as $calc() uses except:

// floor divide operator behaves like / operator, being an 'int divide' that's identical for positive results but not for negatives.


operations - The calculations to perform.


accurate result for extremely large integers
//echo -ag $calcint( ((2 ^ 256) - 1) * ((2 ^ 256) +1) )

fraction removed from output. not affected by fraction being zero
//echo -ag $calcint(48.0 / 10.0) is same as $int($calc(48 / 10))

term with fraction treated as if zero
//echo -ag $calcint(5 + 2.5) is same as 5 + 0

not affected by value 2^96 or greater
//var %ag 79228162514264337593543950335 | echo -a $calcint(1+%a) vs $calc(1+%a) is 79228162514264337593543950336 vs 0

fractional terms created by parenthesis can affect output
//echo -ag $calcint(2 * (48 / 10)) vs $calcint(2 * 48 / 10) is 8 vs 9

If you need floordivide for negative numbers, you must calculate it using / (divide) and % (modulo). Note that $calc() is accurate for a smaller range:
//var -s %numerator -10 , %denominator 3 , %intdivide $calcint(%numerator / %denominator) , %mod $calcint(%numerator % %denominator) , %floordiv %intdivide | if (%intdivide < 0) var -s %floordiv $calcint(%floordiv - $iif(%mod,1,0)) | echo -a %floordiv vs $calc(%numerator // %denominator)
