Std.Decimal.parse

fn

This is a callable function.

What it does

Read a decimal from text, answering None when the text is not one.

There is deliberately no conversion from Float64. A binary float that

prints as 0.1 is not the number 0.1, and letting it become 0.1d

silently would import exactly the error this type exists to avoid.

Read the signature

• The text after the name is the type checked by Pudu.
• Read arrows from left to right: inputs come first, and the final type is returned.
• Names inside [ ] are type arguments, such as the item type held by a collection.
• Option holds Some(value) or None when no value is available.
