Intrinsic Numeric Operations

The following operators are valid for numeric expressions,

• ** -- exponentiation, dyadic operator, for example, 10**2, (evaluated right to left);
• * and / -- multiply and divide, dyadic operators, for example, 10*7/4;
• + and - -- plus and minus or add and subtract, monadic and dyadic operators, for example, -4 and 7+8-3;

All the above operators can be applied to numeric literals, constants, scalar and array objects with the only restriction being that the RHS of the exponentiation operator must be scalar.

Example,

     a = b - c
     f = -3*6/5

Note that operators have a predefined precedence, which defines the order that they are evaluated in, (see Section 12.7).
