POWER: Raising a Value to a Power

POWER raises a base value to a power.

Raise a Value to a Power

POWER(base, power)

where:

base

Numeric

Is the value to raise to a power. The output value has the same data type as the base value. If the base value is integer, negative power values will result in truncation.

power

Numeric

Is the power to which to raise the base value.

Raising a Base Value to a Power

In the following request, POWER returns the value COGS_US/20.00 raised to the power stored in DAYSDELAYED:

DEFINE FILE WF_RETAIL_LITE
BASE=COGS_US/20.00;
POWER1= POWER(COGS_US/20.00,DAYSDELAYED);
END
TABLE FILE WF_RETAIL_LITE
PRINT BASE IN 15 DAYSDELAYED POWER1
BY PRODUCT_CATEGORY
WHERE PRODUCT_CATEGORY EQ 'Computers'
WHERE DAYSDELAYED NE 0
ON TABLE SET PAGE NOPAGE
END

Partial output follows:

Power returns the value COGS_US/20.00 raised to the power stored in DAYSDELAYED.

POWER1= POWER(COGS_US/20.00,DAYSDELAYED)

For base 12.15 and power 3, the value is 1,793.61
