Method GetFloat

options/options.go:237–271

GetFloat retrieves a float64 value from the options. If the key does not exist, GetFloat returns the provided default value. If the key value exists but the value is of a different float or integer type, GetFloat converts it to float64. If the key exists but the value is not a float or integer type,

(key string, def float64)

// GetFloat converts it to float64.
// If the key exists but the value is not a float or integer type, GetFloat panics.
func (o *Options) GetFloat(key string, def float64) float64 {
	v, ok := o.m[key]
	if !ok {
		return def
