SUBST-DEBUG

XLTS.1.
You seem to have given 'SUBST-E-TARGET', which is outside the range that RIES can handle. I will substitute the natural logarithm of this value, which is SUBST-O-TARGET: XLTE.1.

XLTS.2.
The above equations approximate the logarithm of the value you gave. If you solve them for x, you can express your original 'SUBST-E-TARGET' as e^x. (If you do not want this substitution, perform your own transformation. For example, you could give RIES the cube root of your number.) XLTE.2.

XLTS.3.
{*} The number you specified caused a calculation overflow. The limit is approximately 10³⁰⁸. XLTE.3.

XLTS.4.
{*} Unused (error 2) XLTE.4.

XLTS.5.
{*} Your input contains more than one comma. RIES and ORIES treat a comma as a decimal point (the standard in much of the world). Do not separate groups of digits with anything, except for a single '.' or ',' as a decimal point. XLTE.5.

XLTS.6.
{*} Your input 'SUBST-C-TARGET' contains disallowed characters. RIES does not accept expressions, only numbers. Instead of "Sqrt[Pi-Phi]" or "1.111^2", give a plain number, like 1.234321, or 6.02e23 for scientific notation.
{*} This online RIES server does not accept command-line options like --numeric-anagram. To access these options you need to download the source code and compile RIES yourself. XLTE.6.

XLTS.7.
{*} Your input 'SUBST-C-TARGET' appears to be zero. RIES does not accept a zero input. XLTE.7.

XLTS.8.
{*} Your input 'SUBST-C-TARGET' appears to be a non-integer. The 'integer-only expressions' option works only when the target number is an integer. XLTE.8.

XLTS.9.
{*} Your input 'SUBST-C-TARGET' is too large or small for RIES to handle. RIES can directly handle numbers between 10^-6 and 10⁶. XLTE.9.

XLTS.10.
{*} If you give a number larger than 10⁶ using scientific notation (in this case, 'SUBST-E-TARGET'), RIES will automatically take the natural logarithm. XLTE.10.

XLTS.11.
{*} Suggestion:

Take the logarithm of your number:

-6.0221413e23 → -(e^54.75490003)

then use RIES to find an equation for the exponent:

ries 54.75490003 → x-(1/pi+e) = 7²+e

and substitute "ln(-y)" for x in the equation:

ln(-y)-(1/pi+e) = 7²+e

which then solves to:

y = -(e^{(7²+1/pi+2e)}) = -6.02198...×10²³ XLTE.11.

XLTS.12.
{*} Suggestion: Take the cube root of your number, submit it to RIES, then express your original number as "... to the power of 3". XLTE.12.

XLTS.13.
{*} Suggestion: Add a decimal point between two digits: 8675309 → 867.5309. XLTE.13.

XLTS.14.
{*} The allowed format for entering numbers in RIES is: A '+' or '-' sign, ASCII digits '0' through '9' (with one '.' or ',' as a decimal point), and an optional 'e' with exponent. Examples:

-27
1.0307e-27
1047
867.5309
6.022e23

Any input equal to zero (such as -0.0 or 0.0e10) is not considered valid. XLTE.14.

XLTS.15. Your target value: XLTE.15.

XLTS.16. www.mrob.com/ries XLTE.16.

XLTS.17. RIES command: XLTE.17.

XLTS.18. Not executed XLTE.18.

XLTS.19. Your input has been interpreted as 'SUBST-O-TARGET' XLTE.19.

XLTS.20. No RIES output due to an error. XLTE.20.
