Features
Starting with the W series, this product line supports dual-line displays with multiple line playback, constant calculation, chain calculation, similar to the Casio FX-MS series, TI-34 II Explorer Plus.
The upper line shows entered expression (up to 12 characters at a time).
The basic EL-509W, EL-531W models includes 272 functions, which include power/root/logarithm functions, trigonometry functions, factorials, random functions, fractions, angle unit conversion, polar/cartesian coordinate conversion, binary/pental/octal/hexadecimal calculations (includes logical ops), 1-2 variable statistics with 6 regression models (linear, logarithmic, exponential, power, inverse, quadratic). Calculations are done in 14 digits internally.
EL-531WG uses 2 LR44 and solar cells.
EL-531WH runs on 1 AA battery instead of 2 LR44 batteries.
EL-520W adds 52 physical constants, 44 unit conversions, complex number calculation, 2-3 variable linear equation solver, quadratic equation/cubic function equation solver, Newton generic equation solver, numeric derivative/integral functions, formula memory (max 4 formulae, 256 characters total), algebraic substitution (simulation calculation) to EL-509/531W, for total of 419 functions. It is powered by 2 LR44 batteries or light.
EL-506W adds matrix calculation, list calculation (max 4 lists, 16 elements/list) to EL-520W, for total of 469 functions.
EL-500M is a single line version of EL-509W, which contains only the dot matrix line. Dot matrix line only shows 11 characters. Memory register is reduced from 9 to 1. Removed functions include engineering unit display mode, cubic root/power, hyperbolic trigonometry, random dice, random coin, random integer, angle unit conversion, polar/cartesian coordinate conversion, multi-line playback, binary/pental/octal/hexadecimal calculations, 2-variable statistics, 2-key roll-over. However, it adds reduction study, highest common factor/lowest common multiple, quotient/remainder calculation. Total function is 131. The keyboard is not plastic like the others in the lineup.
EL-501W does not support DAL (Direct Algebraic Logic), and only has the 7-segment digit line in EL-509W. It only supports 8-digit mantissa display in scientic notation mode. Functions are further stripped down from EL-500W. Removed functions include last answer recall, nPr/nCr, reduction study, highest common factor/lowest common multiple, quotient/remainder calculation, equation playback. However, it gains cubic power/root, hyperbolic trigonometry, angle unit conversion, polar/cartesian coordinate conversion, complex number calculation, Bin/Oct/Hex calculations (without logical ops) over EL-500W. Total function is 131.

Famous quotes containing the word features:
“Art is the child of Nature; yes,
Her darling child, in whom we trace
The features of the mother’s face,
Her aspect and her attitude.”
—Henry Wadsworth Longfellow (1807–1882)
““It looks as if
Some pallid thing had squashed its features flat
And its eyes shut with overeagerness
To see what people found so interesting
In one another, and had gone to sleep
Of its own stupid lack of understanding,
Or broken its white neck of mushroom stuff
Short off, and died against the windowpane.””
—Robert Frost (1874–1963)
“Each reader discovers for himself that, with respect to the simpler features of nature, succeeding poets have done little else than copy his similes.”
—Henry David Thoreau (1817–1862)
