2.0250405e+07 was parsed as (2.0250405)*1e7, which is not exact in float64. Combine the fractional digits with the exponent first. See valyala#110

2.0250405e+07was parsed as(2.0250405)*1e7, which is not exact in float64 (2.0250404999999996e+07). Combine the fractional digits with the exponent first so the mantissa stays an integer.Fixes #110
