single precision

Refers to a level of coordinate accuracy based on the number of significant digits that can be stored for each coordinate. Single-precision numbers store up to 7 significant digits for each coordinate, retaining a precision of 5 meters in an extent of 1,000,000 meters. ARC/INFO data sets can be stored as either single- or double-precision coordinates. See also double precision.

In the Java language specification, describes a floating point number with 32 bits of data. See also double precision.
