Description copied from class: AbstractConfigurableFloatingPointBitsFromByteArrayUtf8

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

Specified by:

valueOfFloatLiteral in class AbstractConfigurableFloatingPointBitsFromByteArrayUtf8

Parameters:

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

integerStartIndex - the start index (inclusive) of the integer part of the significand inside the string

integerEndIndex - the end index (exclusive) of the integer part of the significand the string

fractionStartIndex - the start index (inclusive) of the fraction part of the significand inside the string

fractionEndIndex - the end index (exclusive) of the fraction part of the significand the string

isSignificandNegative - whether the significand value is negative

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

exponent - the exponent of the float value considering the significand

isSignificandTruncated - whether the significand is truncated

exponentOfTruncatedSignificand - the exponent value of the truncated significand

exponentValue - the exponent of the float value without considering the significand

startIndex - the start index of the literal in str

endIndex - the end index of the literal in str

Returns:

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