Due to its simple operation for key financial calculations, the calculator long ago became the de facto standard among financial professionals.\n\nFunctions included for Statistics, Time Value of Money, Cash Flow Analysis, Amortization, Depreciation, Bonds and calendar functions.\u003cbr clear=\"left\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eConstruction: \u003c\/strong\u003eCase made from a sand-blasted Grade 1 Titanium housing, brown anodized and laser engraved\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eSoftware: \u003c\/strong\u003eARM microcontroller emulating the NUT processor\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eProcessor: \u003c\/strong\u003eLPC1115 32-bit ARM Cortex-M0 microcontroller\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eMemory: \u003c\/strong\u003e64 kB internal flash, 8kB RAM\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eDisplay Type: \u003c\/strong\u003eReflective Positive FSTN\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eDisplay Resolution: \u003c\/strong\u003e132 x 16 pixels\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eDisplay Active Area: \u003c\/strong\u003e69.1 mm x 10.0 mm \/ 2.72\" x 0.39\"\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eDisplay Dot Pitch: \u003c\/strong\u003e524 µm x 626 µm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnectivity (PC): \u003c\/strong\u003eUSB Mini-AB port for firmware update and data exchange via CDC\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eBattery Type: \u003c\/strong\u003e1 x CR2032 lithium coin cell, 3.0 volts\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eBattery Life: \u003c\/strong\u003eUp to 5 years\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eSound: \u003c\/strong\u003e4 kHz resonance frequency Piezo-electric buzzer\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003ePouch: \u003c\/strong\u003eComes with genuine leatherette pouch\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eSize: \u003c\/strong\u003e129 mm x 79 mm x 13 mm \/ 5.08\" x 3.11\" x 0.51\"\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eWeight: \u003c\/strong\u003e150 g \/ 5.29 oz\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eWarranty: \u003c\/strong\u003e5 years\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SwissMicros","offers":[{"title":"New","offer_id":45152795754682,"sku":"SW-DM12L","price":274.95,"currency_code":"USD","in_stock":false},{"title":"Budget - Screen Damage","offer_id":45152795787450,"sku":"SW-DM12L~UD","price":169.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0722\/6821\/8554\/files\/swissmicros-dm12l-rpn-financial-calculator-hp-12c-clone-23_939b2b41-32d3-49a3-883e-14851e6d48f0.png?v=1758859557"},{"product_id":"swissmicros-dm15c-rpn-calculator-credit-card-sized-hp-15c-clone","title":"SwissMicros DM15C RPN Calculator - Credit Card Sized HP-15C Clone","description":"\u003cp\u003eThe DM15C is a high-end scientific programmable calculator with a root-solver and numerical integration, able to handle complex numbers and matrix operations.\u003c\/p\u003e\n\u003cp\u003eThe DM15C also includes Hyperbolic and inverse hyperbolic trig functions;

The alphanumeric LCD screen of the HP-41C revolutionized the way a calculator could be used, providing user-friendliness (for its time) and expandability (keyboard-unassigned functions could be spelled out alphabetically). By using an alphanumeric display, the calculator could tell the user what was going on, displaying meaningful error messages ('ZERO DIVIDE') instead of simply a blinking zero. It could also prompt the user for explicit arguments ('ENTER RADIUS') instead of just displaying a question mark.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction: \u003c\/strong\u003eCase made from a sand-blasted Grade 1 Titanium housing, brown anodized and laser engraved\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSoftware: \u003c\/strong\u003eARM microcontroller emulating the NUT processor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProcessor: \u003c\/strong\u003eLPC1115 32-bit ARM Cortex-M0 microcontroller\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMemory: \u003c\/strong\u003e64 kB internal flash, 8kB RAM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplay Type: \u003c\/strong\u003eReflective Positive FSTN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplay Resolution: \u003c\/strong\u003e132 x 16 pixels\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplay Active Area: \u003c\/strong\u003e69.1 mm x 10.0 mm \/ 2.72\" x 0.39\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplay Dot Pitch: \u003c\/strong\u003e524 µm x 626 µm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnectivity (PC): \u003c\/strong\u003eUSB-C port for firmware update and data exchange via CDC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery Type: \u003c\/strong\u003e1 x CR2032 lithium coin cell, 3.0 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery Life: \u003c\/strong\u003eUp to 5 years\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSound: \u003c\/strong\u003e4 kHz resonance frequency Piezo-electric buzzer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePouch: \u003c\/strong\u003eComes with genuine leatherette pouch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize: \u003c\/strong\u003e88 mm x 58 mm x 9 mm \/ 3.46\" x 2.28\" x 0.39\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight: \u003c\/strong\u003e62 g \/ 2.19 oz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty: \u003c\/strong\u003e5 years\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SwissMicros","offers":[{"title":"New","offer_id":45357842661562,"sku":"SW-DM41C","price":274.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0722\/6821\/8554\/files\/68c03b8e5765f12858b6a71e_drw_dm41c_front_600-p-500.png?v=1764034402"},{"product_id":"hewlett-packard-used-hp-48s-graphing-calculator","title":"Hewlett Packard Used HP-48S Graphing Calculator","description":"\u003cspan class=\"warn\"\u003e3\/7\/26 -
