Chapter 8 - Arithmetic Computation

8.1 - Purpose        top

Perform basic arithmetic operations.

8.2 - Usage        top

Add, subtract, multiply, divide two numbers:

   <arithmetic-instruction> <numerical-variable> <numerical-value>
Compute the negative value of a numerical variable:
   neg <numerical-variable>
Truncate value of a numerical variable to the nearest integer value between that value and 0:
   trunc <numerical-variable>

8.3 - Description        top

The <arithmetic-instruction> must be one of the following:

A <numerical-variable> must be the identifier of a variable whose current value is a string representing a decimal integer or floating-point number.

A <numerical-value> can be either a <numerical-variable>, or a string representing a decimal integer or floating-point number. The value resulting from the arithmetic computation is stored into <numerical-variable>.

Arithmetic computation is always performed by Tefigel in floating-point in decimal base representation.
