Detailed Description

Implements the OP_EXP opcode using C99 math.h exp().

VM opcode snippet included by vm.c. Provides the natural exponential function.

Behavior:

• Pops one numeric operand (int or float).
• Computes e^x in double precision.
• Pushes a VAL_FLOAT result.

Stack effect:

• Pop: x
• Push: exp(x)

Types:

• Accepts VAL_INT and VAL_FLOAT; others raise a runtime error.
