Ríomhairí, Ríomheolaíocht 1. An chuid chodánach neamhdhiúltach de léiriú logartaim. 2. I léiriú snámhphointe, an uimhir a mhéadaítear faoi bhonn an tsnámhphointe intuigthe easpónantaithe le teacht ar an réaduimhir atá á léiriú; mar shampla, léiriú snámhphointe den uimhir 0.0001234 is ea 0.1234-3, áit arb é .1234 an mhír fosphointe agus arb é -3 an t-easpónant. Comhchiallach le mír fosphointe. 3. I bhformáid shnámhphointe, an uimhir a théann roimh an E. Is éard atá sa luach a léirítear ná toradh na maintíse agus cumhacht 10 mar a shonraíonn an t-easpónant é.
Computers, Computer Science 1. The non-negative fractional part of the representation of a logarithm. 2. In a floating-point representation, the numeral that is multiplied by the exponentiated implicit floating-point base to determine the real number represented; for example, a floating-point representation of the number 0.0001234 is 0.1234-3, where .1234 is the fixed-point part and -3 is the exponent. Synonymous with fixed-point part. 3. In floating-point format, the number that precedes the E. The value represented is the product of the mantissa and the power of 10 specified by the exponent.
