2.5MATHEMATICAL FUNCTIONS

This section describes the mathematical functions provided by SCOL for substitution, calculation and judgement.

With SCOL, mathematical functions can either be used independently or included in a command. A mathematical function included in a command may be a computational expression (in which the result of a calculation is substituted into a variable), or a logical expression (such as greater-or-less- than constructs and true/false constructs).

Mathematical functions provided by SCOL are shown in Table 2.3.

Note that 0/0 will return a -1, and 0 ^ 0 will return a 1. One would normally expect these operations to return an error, but be careful because they don't.

Table 2.3 Mathematical functions

Type	Operand	Function	Example
Arithmetic	^	Exponentiation	A ^ B (A to the B power)
functions	-	Minus sign	-A
	*, /	Multiplication, division	A * B, A / B
	+, -	Addition, subtraction	A + B, A – B
	MOD	Remainder	A MOD B (The remainder when A is
			divided by B.)
	=	Substitution	A = B (Puts the value of B into A.)
Relational	= =	Equal	A = = B
function	< >, > <	Not equal	A < > B, A > < B
	<	Less than	A < B
	>	Greater than	A > B
	< =, = <	Less than or equal	A < = B, A = < B
	> =, = >	Greater than or equal	A > = B, A = > B
Logical	AND	Logical product	A AND B
operands	OR	Logical sum	A OR B
	NOT	Negation	NOT A
Functions	SIN	Sine	SIN (A)
	COS	Cosine	COS (A)
	TAN	Tangent	TAN (A)
	ASIN	Arcsine	ASIN (A)
	ACOS	Arccosine	ACOS (A)
