HyperMath supplies a range of useful functions for processing and manipulating strings in its standard library.  See String Library for more information.  Below are some examples of using the string library.

> print(StrFind("hello HyperMath user", "HyperMath")) // find substring "HyperMath"

7       15          //H occurs at 7th space & h occurs at 15th space

 

> print(StrFind("hello HyperMath user", "l+")) // find one or more occurrences of "l"

3       4

 

> print(StrFormat("%.7f", PI)) // format a number

3.1415927

 

> print(StrFormat("%s", "HyperMath")) // format a string

 HyperMath

 

> print(StrFormat("%s %.7f", "HyperMath", PI)) // Multiple formats

 HyperMath 3.1415927

 

> print(StrFormat("%s %.3f", "HyperMath", PI)) // Multiple formats

 HyperMath 3.142

 

> pi = StrFormat("%.3f", PI)

> print(pi)
