2.5 Number Range

All values used in arithmetic operations or in any context requiring a_numeric interpretation are within the inclusive intervals (–10²⁵, –10^–25) or (10^–25, 10²⁵), or are zero.

The accuracy of any value used in arithmetic operations or in any context requiring a numeric interpretation is nine significant digits.

Programmers should exercise caution in the use of noninteger arithmetic. In general, arithmetic operations on noninteger operands or arithmetic operations which produce noninteger results cannot be expected to be exact. In particular, noninteger arithmetic can yield unexpected results when used in loop control or arithmetic tests.
