Details
Real Float Number

Expression |
[+-]?+(?>\d++\.?+\d*+|\d*+\.?+\d++)

Description |
This regex is designed to fail fast (using possessive quantifiers) while still matching a floating decimal number all the time. Won't match scientific notation or fractions. Can be combined with other patterns.
Note: This site's tester does not support them.
If your language does not support possessive quantifiers try the following:
(?>[+-]?)(?>(?>\d+)(?>\.?)(?>\d*)|(?>\d*)(?>\.?)(?>\d+))
