Parameters
str:byte[]

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

startIndex:int

the start index (inclusive) of the float literal inside the string

endIndex:int

the end index (exclusive) of the float literal inside the string

isNegative:boolean

whether the float value is negative

significand:long

the significand of the float value (can be truncated)

exponent:int

the exponent of the float value

isSignificandTruncated:boolean
