Arithmetic underflow - Wikipedia

WebThe term floating point refers to the fact that the number's radix point can "float" anywhere to the left, right, or between the significant digits of the number. This position is indicated by the exponent, so floating point can be considered a form of scientific notation . WebIEEE Floating-Point Arithmetic. IEEE arithmetic is a relatively new way of dealing with arithmetic operations that result in such problems as invalid, division by zero, overflow, underflow, or inexact. The differences are in rounding, handling numbers near zero, and handling numbers near the machine maximum. grantchester anna lawson

Floating point underflow

WebIn IEEE floating-point format, the radix point occurs before the significand, and there is an implicit leading bit of 1. Gradual underflow allows the implicit leading bit to be cleared to 0 and shifts the radix point into the significant when the result of a floating-point computation would otherwise underflow.
