The '''float''' [[class]] in [[C Sharp]] is a [[data type]] which can store positive and negative '''decimal''' numbers in [[Variable|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 [[Byte|bytes]], or 32 [[Bit|bits]].

They are usually [[Floating point accuracy|accurate]] up to around 7 digits.

If you need more [[precision]] or larger/smaller numbers, you can instead use the [[C Sharp double|double]] [[data type]].

== Example ==
<syntaxhighlight lang="cs" line="1">
float a;
float b = 539.72;
float c = (float)781; // 781.0
</syntaxhighlight>
