BIGMODPOW$ Function

BIGMODPOW$(string-expression, string-expression, string-expression)

Computes modular exponentiation on arbitrary precision integers, returning ((A^E) \bmod M) as a string.

Examples

PRINT BIGMODPOW$("2", "10", "1000")

Produces "24".

PRINT BIGMODPOW$("5", "3", "13")

Produces "8".

PRINT BIGMODPOW$("123456789", "2", "100000")

Produces "521".

Notes

• All inputs must be valid base-10 integer strings.
• Efficient for large values (uses modular exponentiation, not naive power).
• Modulus must be non-zero.
• Negative bases are supported; exponent must be non-negative.
• Result is always in the range 0 to M-1.
• Result is returned as a decimal string.
