4.5 Math commands

There are the commands to use the AMMP math routines. The commands support the VAR type that combines the possibility to use variable names and float/integer constant. You must remember that 1 and 1.0 constants don't have the same meaning: the first one is an integer constant and the second one is a floating point constant.

ADD   (VAR)Var1   (VAR)Var2

Return message:
Result of the arithmetic operation.

Example:
ADD    a   1;

See also:

Cosine trigonometric function.

Return message:
Result of the trigonometric function.

Example:
COS    0.5;

See also:

MUL   (VAR)Var1   (VAR)Var2
 

Arithmetic multiplication between two terms.

Return message:
Result of the arithmetic operation.

Example:
MUL   a   3.0;

See also:
ADD, DIV, SUB.

Return message:
The current time in floating point format.

Example:
TIME    tm;

See also:
None.
