14.1.6 Mathematical Expressions
In addition to using variables and constants, certain script commands also allow
you to specify a mathematical expression (see 14.1.7 “Script Commands That
Accept Numeric Variables and Expressions”, 14-12).
An expression is constructed from floating point numbers, variables and
operators. The following operators are available:
Tab. 14-5 Expressions that can be used with variables
Operator
Function
+ addition
- subtraction
* multiplication
/ division
% modulo division (division remainder)
( ) parenthesis, used to specify the evaluation
order
Examples of valid expressions:
volume
volume + 10.5
volume * 2
volume + (samples * 2)
3 + 4 * 5
Spaces in expressions are ignored. Multiplication and division have precedence
over addition and subtraction.
Modulo division returns the remainder of a division as an integer.
Examples: 13 % 8 = 5, 49 % 8 = 1
If e.g. the number of samples in a pipetting operation is not an exact multiple of
the number of tips you are using, modulo division can be used to calculate how
many samples you need to pipette in the last cycle of a pipetting loop. Take care
when using modulo division if one or both of the arguments are negative values.
