▸ getClassName(): string

string

▸ Static convertFloatStepToDouble(step): number

This is needed because a float such as 0.002 gets transformed to 0.00200000123 when doing a single (double) cast.

number

result The converted number.

▸ Static getClassName(): string

string

▸ Static getMinimumFractionDigits(step): number

Gets the Minimum fraction digits

number

result The minimum digits.

▸ Static getNormalizedLineValue(minValue, stepIndex, step): number

Fixes precision calculator of inline and xline numbers. Can be used for time/depth as well result is always >= min never pass floats, always pass doubles works with negative of positive steps

number

normalizedValue The normalized line value.

▸ Static getNormalizedStepCount(minValue, value, step): number

Fixed precision calculator of step count. same as getNormalizedStepIndex, with 1 added result is always >= 1 never pass floats, always pass doubles don't use arbitrary step values

number

index The normalized step index.

▸ Static getNormalizedStepIndex(minValue, value, step): number

Fixed precision calculator of step count. same as getNormalizedStepIndex, with 1 added result is always >= 1 never pass floats, always pass doubles don't use arbitrary step values

Throws

Error if value < minValue

number

index The normalized step index.

▸ Static getNormalizedStepMultiplier(step): number

Finds the number of digits after the dot never pass floats, always pass doubles

Throws

Error if step is too big

number

multiplier The number of digits

▸ Static getRelativeLineValue(referenceValue, stepIndex, step): number

fixes precision calculator of inline and xline numbers. Can be used for time/depth as well example: StepPrecisionUtil.getNormalizedLineValue(1, 50, 0.1) => 6 example: StepPrecisionUtil.getNormalizedLineValue(1, -50, -0.1) => 6 To use when the reference value is not the minimum value never pass floats, always pass doubles you might want to pass Math(step) as step

number

relativeValue The calculated relative value.

▸ Static getRelativeStepIndex(referenceValue, value, step): number

Fixed precision calculator of step indexes. add one to get a step count example: getNormalizedStepIndex(1, 1, 0.1) => 0 example: getNormalizedStepIndex(1, 6, 0.1) => 50 example: getNormalizedStepIndex(1, 6, -0.1) => -50 To use when the reference value is not the minimum value never pass floats, always pass doubles you might want to pass Math(step) as step don't use arbitrary step values

number

index The relative index.
