C Sharp float

The float class in C Sharp is a data type which can store positive and negative decimal numbers in variables.

See Floating point for generic information about what floats can represent and how they are represented in memory.

Size

A float in C# is represented by 4 bytes, or 32 bits.

They are usually accurate up to around 7 digits.

If you need more precision or larger/smaller numbers, you can instead use the double data type.

Example

float a;
float b = 539.72;
float c = (float)781; // 781.0
