Details

You must keep in mind that floating-point calculations are inherently imprecise. Not every value can be converted into its exact floating-point representation. Also, strtof can be invoked implicitly. The example below illustrates this.

Examples

Tibbo BASIC

							dim r1 as real
							dim s as string
							 
							s="456.125"
							r1=strtof(s) 'r1 will be equal to 456.125. This conversion will be done without errors.
							s="123.200"
							r1=strtof(s) '123.200 will be converted with errors. Actual result will be 123.25.
							r1=s 'implicit invocation. Same result as for the line above.
