EXPONENT()
Evaluate the exponent of a floating point number
Syntax
EXPONENT( <nFloatingPointNumber> ) --> nExponent
Arguments
<nFloatingPointNumber> Designate any Harbour number.
Returns
EXPONENT() returns the exponent of the <nFloatingPointNumber> number in base 2.
Description
This function supplements MANTISSA() to return the exponent of the <nFloatingPointNumber> number.
Values > 1 or values < -1 return a positive number 0 to 1023.
Values < 1 or values > -1 return a negative number -1 to -1023.
The EXPONENT( 0 ), return 0.
The following calculation reproduces the original value:
2ˆEXPONENT(<nFloatingPointNumber>) * MANTISSA(<nFloatingPointNumber>) = <nFloatingPointNumber>
