There are some differences between the parser in the Mathematics VIs and the Formula Node. The following table outlines these differences.

Element	Formula Node	Parser VI Routines
Variables	No restrictions	Only a, a0, ..., a9, ... z, z0, ..., z9, are valid
Binary functions	max, min, mod, rem	Not available
Additional math functions	Not available	gamma, ci, si, spike, step, square
Logical, conditional, inequality, equality	?:,, &&, !=, ==, <, >, <=, >=	Not available
	pi	pi(1) =, pi(2) = 2, 2pi or 2(pi) will return an error
Exponentiation	**	^

The precedence of operators is the same for the Mathematics VIs as in the Formula Node. Refer to Formula Parsing VIs for more information about specific Formula Parsing VIs.

All Mathematics VI functions use the following syntax:

function (argument)
