Fa'amatalaga Fa'atino
- O le IEEE Standard for Floating-Point Arithmetic (IEEE 754) o se tulaga faʻapitoa mo le faʻaogaina o mea faʻapipiʻi. O le upu floating-point e faasino i le radix point o le numera (decimal point or binary point), lea e tuu i soo se mea e tusa ai ma numera taua o le numera.
O se numera opeopea e masani ona fa'aalia i le fa'amatalaga faasaienisi, faatasi ai ma se vaega ninii (F), ma se fa'aupuga (E) o se radix (r), i foliga o le F × r^E. O numera tesi e fa'aaoga ai le radix o le 10 (F × 10^E); a'o numera binary e fa'aaoga ai le radix o le 2 (F × 2^E). - E le tulaga ese le fa'atusaina o le numera fa'afefete. Mo example, o le numera 55.66 o loʻo faʻatusalia e 5.566 × 10^1, 0.5566 × 10^2, 0.05566 × 10^3, ma isi. O le vaega ninii e masani. I le tulaga masani, e na o le tasi le numera e le-zero i luma o le radix point. Mo example, numera tesimale 123.4567 ua fa'avasegaina o le 1.234567 × 10^2; numera binary 1010.1011B o loʻo faʻatulagaina o le 1.0101011B × 2^3.
- E taua le maitauina o numera o loʻo faʻafefeteina e afaina i le leiloa o le saʻo pe a faʻatusalia i se numera tumau o bits (mo ex.ample, 32-bit poʻo le 64-bit). E mafua ona o loʻo i ai se numera e le gata o numera moni (tusa lava i totonu o se laʻititi laʻititi mai le 0.0 i le 0.1). I le isi itu, a
n- bit binary pattern o lo'o fa'atusalia se numera ma'oti 2^n. O lea la, e le o fa'atusa uma numera moni. O le fa'atatau lata ane o lo'o fa'aaogaina, lea e mafua ai le leiloa o le sa'o.
O le numera fa'a'opeopea sa'o e tasi o lo'o fa'atusalia e fa'apea:
- Laiti fa'ailoga: 1-bit
- Lautele lautele: 8 bits
- Taua sa'o: 24 bits (23 bits o lo'o teuina manino)

O le numera fa'a'a'e fa'ato'a sa'o lua o lo'o fa'atusalia e fa'apea:
- Laiti fa'ailoga: 1-bit
- Lautele lautele: 11 bits
- Taua sa'o: 53 bits (52 bits o lo'o teuina manino)
Ata 2-2. 64-bit Frame 
O le CoreFPU o le tuʻufaʻatasiga pito i luga o le faʻaliliuga e lua (Faʻamau i le Float point ma Float i Faʻamau) ma le tolu faʻasologa (FP ADD, FP SUB, ma le FP MULT). E mafai e le tagata faʻaoga ona faʻatulagaina soʻo se tasi o gaioiga e faʻavae i luga o le manaʻoga ina ia faʻaaogaina punaoa mo le gaioiga filifilia.

Manatua faʻamatalaga o loʻo i lalo o le faʻaogaina o le puipuiga o tulafono i luga o oloa Microchip:
- O oloa Microchip e fetaui ma faʻamatalaga o loʻo i totonu o la latou Pepa Faʻamatalaga Microchip.
- E talitonu Microchip o lona aiga o oloa e saogalemu pe a faʻaaogaina i le auala faʻamoemoeina, i totonu o faʻamatalaga faʻaogaina, ma i lalo o tulaga masani.
- Microchip fa'atauaina ma puipuia fa'amalosi ana aia tatau tau meatotino. O taumafaiga e soli le tulafono o le puipuiga o oloa Microchip e matua fa'asaina ma e ono solia ai le Digital Millennium Copyright Act.
- E le mafai e le Microchip poʻo se isi mea gaosi semiconductor ona faʻamaonia le saogalemu o lana tulafono. O le puipuiga o tulafono laiti e le o lona uiga tatou te faʻamautinoa o le oloa e "le mafai ona motusia". O le puipuiga o tulafono laiti o lo'o fa'asolosolo pea. Microchip ua tuuto atu i le faʻaauauina pea o le faʻaleleia atili o uiga puipuia o tulafono a tatou oloa.
