1. Natural Index EXP
1.1. Instruction Description#
The instruction calculates the IN power exponent of e and places the result in OUT.
EXP(IN) = OUT
To elevate any real number to a power of another real number, including fractional exponentiation: combine the "natural exponent" instruction with the "natural logarithm" instruction. For example, to raise X to a power of Y, use the following formula:
EXP (Y * LN (X))
Example: Cube of 5=5 ^ 3=EXP (3 * LN (5))=125
1.2. The valid operands of the instruction#
| Input/Output | Data Type | operand | Description |
|---|---|---|---|
| IN | 32-bit real number | D/K/FD, local variable (LF) | input |
| OUT | 32-bit real number | D/FD, local variable (LF) | output |
