Method TryParseNumber

Namespace: DocWright.Dom.Fields

Assembly: DocWright.Dom.dll

TryParseNumber(string?, CultureInfo, out double)

Parses a field operand as a number, by Word's rule.

public static bool TryParseNumber(string? text, CultureInfo culture, out double value)

Parameters

text string: The operand text.
culture CultureInfo: The culture supplying the symbol and separators.
value double: The parsed value.

Returns

bool: true if the operand is numeric.

Remarks

Accepted: a leading minus, a leading currency symbol, thousands separators, a leading or trailing decimal point, leading zeros, and a trailing percent sign (which divides by 100, so 50% is 0.5).

Rejected, each because the oracle rejected it: a parenthesized negative ((5) < (4) is false, so (5) is text — the same reading WQ-0006 found for table cells), scientific notation (1e2 = 100 is false), and a leading plus (+5 = 5 is false). Phase 14 accepted all three; the first two were invented outright and the third came in with Float.

The currency symbol and separators recognized are culture's, which is why the measurements were captured on an en-NZ Word where $ is the local symbol.
