Method Details

valueOfFloatLiteral

long valueOfFloatLiteral(CharSequence str,
 int startIndex,
 int endIndex,
 boolean isNegative,
 long significand,
 int exponent,
 boolean isSignificandTruncated,
 int exponentOfTruncatedSignificand)

Description copied from class: AbstractJsonFloatingPointBitsFromCharSequence

Computes a float value from the given components of a number literal.

Specified by:

valueOfFloatLiteral in class AbstractJsonFloatingPointBitsFromCharSequence

Parameters:

str - the string that contains the number literal (and maybe more)

startIndex - the start index (inclusive) of the number literal inside the string

endIndex - the end index (exclusive) of the number literal inside the string

isNegative - whether the float value is negative

significand - the significand of the float value (can be truncated)

exponent - the exponent of the float value

isSignificandTruncated - whether the significand is truncated

exponentOfTruncatedSignificand - the exponent value of the truncated significand

Returns:

the bit pattern of the parsed value, if the input is legal; otherwise, -1L.
