double precision

[¦dəb·əl prə′sizh·ən]
(computer science)
The use of two computer words to represent a double-length number.

double precision

Using two computer words instead of one to hold a number used for calculations, thus allowing twice as large a number for more arithmetic precision. Contrast with single precision.
