The type float specifies a single-precision value that uses 32 bits of storage. Single
precision is faster on some processors and takes half as much space as double precision,
but will become imprecise when the values are either very large or very small. Variables
of type float are useful when you need a fractional component, but don’t require a
large degree of precision. For example, float can be useful when representing dollars
and cents.
Here are some example float variable declarations:
float hightemp, lowtemp;
