dc(1) MPE/iX Shell and Utilities dc(1)

Message: scale too big

Cause: You speciﬁed a scaling factor that was too large for dc to handle.

Action: Specify a smaller scaling factor.

Message: sqrt of negative number

Cause: You attempted to take the square root of a negative number.

Action: Only use the v (square root) operator on positive numbers.

Message: stack too deep

Cause: You attempted to put more values on the stack than it was able to hold. The

maximum size of the stack is limited by the size of the maximum integer your

system can represent.

Action: Check for uncontrolled recursion.

Message: string is too long

Cause: You speciﬁed a string that is too long for dc to handle.

Action: Split the string into smaller strings.

LIMITS

Maximum array index: 2047.

Maximum exponent in an exponentiation operation: 9999.

Maximum input buffer size (line length): 1000 characters.

Maximum scaling factor: 99.

Maximum stack depth: MAXINT (that is, the size of the largest positive integer that can be

supported by the hardware).

PORTABILITY

UNIX System V.
