warning C4244: '=' : conversion from 'unsigned int' to 'float', possible loss of data
Shouldn't a float be able to handle any value from an int?
unsigned int: 0 to 4,294,967,295
float 3.4E +/- 38 (7 digits)
Wiki:
The advantage of floating-point representation over fixed-point (andinteger) representation is that it can support a much wider range of values.
Any insight would be helpful, thanks.

To convert an integer data type to float you can wrap the integer with float64() or float32. Explanation: Firstly we declare a variable x of type int64 with a value of 5. Then we wrap x with float64(), which converts the integer 5 to float value of 5.00.
'unsigned int' and 'float' both use 32 bits to store values. Since a float has a larger range, it necessarily sacrifices some precision. This means that there are some unsigned int values that cannot be accurately represented in a float.
The utoa() function coverts the unsigned integer n into a character string. The string is placed in the buffer passed, which must be large enough to hold the output. The radix values can be OCTAL, DECIMAL, or HEX.
To convert a signed integer to an unsigned integer, or to convert an unsigned integer to a signed integer you need only use a cast. For example: int a = 6; unsigned int b; int c; b = (unsigned int)a; c = (int)b; Actually in many cases you can dispense with the cast.

While float supports a wider range of values than unsigned int, it does so with less accuracy. Floats have a 23-bit mantissa which, as you posted, is only about 7 decimal digits. unsigned ints support over 9 decimal digits.
Suggestion: use double, not float.
Edit:
Actually, I retract that suggestion; floating-point and integer data types are fundamentally different and are not directly convertible. What integer value do you expect to get for Single.MaxValue? For Single.NegativeInfinity? Explaining why you want to convert from float to int would be helpful.
