Precision and calculation record
Rounding changes displayed numbers, not the calculation. Text, fractions, matrices and CSV schedules keep their own formatting. Automatic keeps up to 12 significant digits, with money shown to cents where applicable.
Step-by-step calculation
Inputs are substituted below. Each line evaluates the next operation; intermediate values are displayed to 12 significant digits while the calculation uses full precision.
    Saved scenario
    Save the current answer, then change an input to compare. This clears when you leave.
    Formula and assumptions
    Enter the perpendicular force component. Positive and negative signs identify opposite rotational directions, not fastener tightening specifications.
    Automatic precision shows numbers to 12 significant digits. Thousands separators such as 1,000 are accepted; use a dot for decimals.
    Scratch calculator
    Use +, −, ×, ÷, parentheses and %. A percentage is divided by 100. This does not change the main tool.
    Reset reloads the tool with its starting values and releases open files and device controls. Saved drafts stay on this device until you delete them.
    Links include your inputs and settings. Anyone with the link can see them, so leave out private text. Files and generated results are left out; random draws run again.
