## Overview

The Rounding Calculator is a straightforward utility designed to quickly round numbers to your exact specifications. Whether you need to round to the nearest integer, a specific number of decimal places, or to the nearest ten or hundred, this tool provides instant, accurate results for financial reporting, academic exercises, or data formatting.

## Inputs

- **Number Input** (text): e.g. 123.4567
- **Rounding Mode** (select)
- **Decimal Places** (number)

## When to use

- Formatting financial figures for reports and dashboards.
- Simplifying precise scientific or mathematical data for general audiences.
- Standardizing numerical inputs to a consistent decimal length.

## How it works

- Enter your target number into the Number Input field.
- Select your desired rounding mode, such as nearest integer, decimal places, nearest 10, or nearest 100.
- If using the decimal places mode, specify the exact number of decimal places required.
- View the instantly calculated rounded value in the output.

## Use cases

- Rounding currency values to exactly two decimal places for invoices and accounting software.
- Estimating large population sizes or inventory counts to the nearest hundred for quick summaries.
- Adjusting precise sensor readings to the nearest integer for simplified data logging.

## Frequently asked questions

### What rounding modes are supported?

You can round to the nearest integer, a specific number of decimal places, the nearest 10, or the nearest 100.

### How many decimal places can I round to?

You can specify anywhere from 0 to 12 decimal places when using the decimal places mode.

### Can I round negative numbers?

Yes, the calculator handles both positive and negative numbers accurately based on standard rounding rules.

### What happens if I select nearest 100 for the number 45?

The number 45 will round down to 0, as it is less than 50. A number like 50 or above would round up to 100.

### Is this tool suitable for financial calculations?

Yes, it is perfect for rounding currency values to two decimal places for standard financial reporting.

Three modes: solve COP (given Q_c and W), solve cooling capacity (given COP and W), or solve input power (given COP and Q_c). Capacity in W/kW/BTU·h⁻¹/ton/kcal·h⁻¹, power in W/kW/hp; all converted to W internally.

Also returns the saturation vapour pressure P_ws, actual partial pressure P_w, and absolute humidity ρ_v (kg/m³). Three input modes: relative humidity φ (natural ventilated), August natural-ventilated wet-bulb T_w, or aspirated (Assmann) wet-bulb T_wa. Temperature in °C/K/°F; all reported temperatures are in the selected Temperature Unit.
- [Drag Force Calculator (F_D = ½·ρ·v²·C_D·A)](https://elysiatools.com/en/tools/drag-force-calculator): Compute the drag force on a body in a fluid stream: F_D = ½·ρ·v²·C_D·A (N), where ρ is the fluid density, v the free-stream velocity, C_D the drag coefficient (shape- and Reynolds-dependent), and A the reference (frontal projected) area. A built-in shape library supplies typical high-Re C_D values: sphere 0.47, hemisphere 0.42, long cylinder 0.81, disk/flat plate 1.17, cube 1.05, streamlined airfoil 0.04, long streamlined ellipsoid 0.07, cone 0.50; or choose 'Custom' to enter C_D directly. Optionally, with dynamic viscosity μ and characteristic length L, the Reynolds number Re = ρ·v·L/μ is computed, and the power dissipated by drag P = F_D·v (W). Density in kg/m³/g/cm³, velocity in m/s/km/h, area in m²/cm²/mm², length in m/cm/mm.

- [Heat Exchanger ε-NTU Calculator (Effectiveness-NTU Method)](https://elysiatools.com/en/tools/heat-exchanger-ntu): Compute the effectiveness (ε) of a heat exchanger by the ε-NTU method. C*=C_min/C_max (0..1), NTU=U·A/C_min, q_max=C_min·(T_h,in-T_c,in), and ε=q_actual/q_max. Supports four arrangements: Parallel flow ε=\[1-exp(-NTU(1+C*))\]/(1+C*); Counter flow ε=\[1-exp(-NTU(1-C*))\]/\[1-C*·exp(-NTU(1-C*))\], or NTU/(1+NTU) when C*=1; Shell-and-tube 1-2 ε=2/\[1+C*+√(1+C*²)·(1+exp(-NTU√(1+C*²)))/(1-exp(-NTU√(1+C*²)))\]; Crossflow (both unmixed) ε=1-exp{(NTU^0.22/C*)·\[exp(-C*·NTU^0.78)-1\]}. When C*=0 (phase change on one side, boiler/condenser) every arrangement gives ε=1-exp(-NTU). Optionally supply T_h,in and T_c,in to recover the actual heat-transfer rate q=ε·q_max and both outlet temperatures. Temperatures are used only as differences: Δ°C=ΔK and Δ°F×5/9=ΔK.
