Question: I want to print out the full legitimate value of some large summation of floats, but when floats are large enough you get this notation such as "1.01383e+007". How can you get the legitimate value?

Answer: 
An important characteristic of floating point is that they do not have precision associated with all the significant figures back to the decimal point for large values. The "scientific" display reasonably reflects the inherent internal storage realities.

If you want 10138300 (for example) to appear, use a datatype which has more significant figures, such as `double` in the C family languages for values up to 1015 or so. Or use an extended precision integer representation, such as `long` or `long long` depending on the CPU architecture and programming language or environment.
The `float` data type does not store the precise value, and hence it is not possible to print out the exact value.

In a `float`, 32 bits are divided between three distinct parts: The sign bit, the exponent and the mantissa like: `S EEEEEEEE MMMMMMMMMMMMMMMMMMMMMMM`

In simpler terms, instead of storing the precise "12345678", `float` data type will only store "1.23\*10^7" (and `double` data type will store "1.2345\*10^7"). Other digits are lost.

Maybe you can look into the "Big Integer" library in C++ if you are interested in the precise value of a large number.
