toNumber

public java.lang.Number toNumber(java.lang.String s)

Description copied from class: ArithmeticEngine

Should be able to parse all FTL numerical literals, Java Double toString results, and XML Schema numbers. This means these should be parsed successfully, except if the arithmetical engine couldn't support the resulting value anyway (such as NaN, infinite, even non-integers): -123.45, 1.5e3, 1.5E3, 0005, +0, -0, NaN, INF, -INF, Infinity, -Infinity.

Specified by:
