twStr2Num( cValue )
----------------------------------------------------------------------------
The functions twDec2Sci(), twSci2Dec(), twStr2Num() and
twNum2Str() attempt to provide a temporary solution to Clipper's
inability to display floating point numbers.
twStr2Num() attempts to return a numeric value for an string
representation of a number in the range 10-300 to 10300 when it
is formatted with either STR() or twDec2Sci(). IF in STR() format,
VAL() is used. If in scientific notation, twSci2Dec() is used.
NOTE: Numbers outside the MSC calculation range will result in a
MSC error which cannot be trapped with ERRORSYS.
Arguments:
cValue - 'C' String representation of a number formatted with
either STR() or twDec2Sci().
Return:
Numeric value or crash if out of range of MSC.
Example:
twStr2Num( "345.56" ) -> 345.56
twStr2Num( "2.3456E12") -> 2.3456 * 1012
