formatExponent

public int formatExponent(char[] result,
                          int i,
                          boolean expSign,
                          int minExpDigits)

Appends decExponent to result string. Returns i plus the number of chars written.

Implementation may assume that exponent has 3 or fewer digits.

For example, given decExponent = 2, formatExponent(result, 5, true, 2) will write '0' into result[5] and '2' into result[6] and return 7.

Parameters:

result - Result buffer

i - Initial offset into result buffer

expSign - Whether to print a '+' sign if exponent is positive (always prints '-' if negative)

minExpDigits - Minimum number of digits to write

Returns:

Offset into result buffer after writing chars
