Have a problem in Computing a values.

Example:
Calculate--> FIELD1 ^(-0.9256)

FIELD1 = Can be 0.95 or 2 or 0.6654 etc...
^ - Exponential

Can anybody give me sample code on CAR File?

Thanks

DEFINE FILE CAR
FIELD1/D12.9 WITH DEALER_COST = 2;
FIELD2/D12.9 WITH DEALER_COST = .95;
FIELD3/D12.9 WITH DEALER_COST = .6654;
END
TABLE FILE CAR
PRINT FIELD1
COMPUTE EXP1/D12.9 = FIELD1 ** (-0.9256);
FIELD2
COMPUTE EXP2/D12.9 = FIELD2 ** (-0.9256);
FIELD3
COMPUTE EXP3/D12.9 = FIELD3 ** (-0.9256);
WHERE RECORDLIMIT EQ 1
END


Gives
FIELD1 EXP1 FIELD2 EXP2 FIELD3 EXP3
2.000000000 .526461523 .950000000 1.048622159 .665400000 1.457990061

Somebody have a scientific calendar to check the numbers. Since basically a negative power means raise to the power and divide into one.
