Difference between getc(), getchar(), getch() and getche(), Difference between %d and %i format specifier in C language. What is the Precision Difference Between Float and Double Datatypes? The other data type is called fixed point, because the decimal point does not move. The main difference is Floats and Doubles are binary floating point types and a Decimal will store the value as a … float has 7 decimal digits of precision. If an answer is required to have negligible difference from the actual answer, number of decimal places required will be many thus will dictate that double to be in use.Float will chop off some decimal places part thus reducing the accuracy. The float and double data types are used to store numerical values with decimal points. float vs double.

Feb 28, 2012 02:07 AM | karthicks | LINK hi , its all about size matters i.e how much size of data it can hold It is more conventional for C-style language programmers to use float than Single. The decimal type is not the underlying type in C #, so using it will … I've been coding with C# and ASP.NET for a long time.In all of that time, I haven't really had a need to figure out the nitty-gritty differences between float and double, or between decimal and pretty much any other type. You don't want to say that it's better than Adobe Photoshop? The difference between the two is that double is more precise than float. float has 23 mantissa bits + 1 hidden bit: log(2 24)÷log(10) = 7.22 digits. A float is a "floating point number" (vs fixed point, ie. EDIT: That's double the size in terms of bit representation, not double like "times 2" So if a float was 32 bits (I think it is off-hand, but I'm not positive), a double would be 64 bits. Float is a 32-bit single-precision floating point type with range 3.4 x 10 38 to + 3.4 x 10 38. float is a 32 bit IEEE 754 single precision Floating Point Number1 bit for the sign, (8 bits for the exponent, and 23* for the value), i.e. Double Type Number = 3.9123482393 Float Type Number = 3.912348.
